Probably a nerdy thread but I figured it would be a good addition right about now with all the monotony going around in here.

:D


So anyhow, I got my card on launch day. Scored a reference model Gigabyte card for $575 (overnight included). I needed a card because I sold my 580 a month before and was desperate for a new card. I had to resort to my 4870 Tri Fire setup :wub: from wayyy back.

The 4870's worked fine but the 1gig vram limit was painful at times considering that I game part time on a 2560 screen and microstutter got the best of me here and there. :'(

The 7970 has been a treat ever since I popped it in my rig. The card was pleasantly less power hungry than my last 3 setups and definately the fastest single gpu at the time.

After a few days confirming that the card performed flawlessly at stock, I began overclocking. :eek: A short time later it was apparent my card was a great overclocker.

From then on I set 1125/1575 (ccc limit) and gamed regularly without issue for the next few months.

While the card can be made to be noisy, you can keep it cool under a reasonable rpm without much tweaking.

Drivers have been slow which has been annoying but I haven't had any problems and is mostly moot. :\

Now for the last 2 weeks i have undergone fine(r) tuned overclocks and have been running 1225/1650 with ease @1.25v. Card still can be kept at a reasonable noise level with good temps.

Performance is awesome but I'm always on pursuit for higher frame rates with better IQ settings. ():) 3gb of ram helped out bigtime in Skyrim

It's nice to see the price has come down some in the recent weeks making it an attractive buy again. :thumbsup:

I'm really looking forward to a "4890" type release in the future.


**edit**


----or better yet---

7970 ---wait for it--- *ULTRA* That would be the slickest PR move ever. With an attitude of screw power consumption in the name of performance, officially release a new sku dubbed Ultra that delivers everything associated with the title. 6gb, fancy cooling, and you can guess it...... xxx mhz.

**edit**

I now have a GTX 680. I made a local card for card trade for an evga GTX 680.

I was sad to see my card go because, honestly.. I fell like the 7970 is/was one of my favorite cards in the past 5 years, only second to my 8800 GTX.

The 7970 was a joy to own from the very second I popped it in my rig.

So, initial impressions of the 680 are as follows. I really like the feel of nVidia's control panel. Always have, Always will. I wish there was something like Overdrive built into the drivers but oh well.

Overclocking--

My 680 is definately a good overclocker and I'm still playing around with clockspeeds but something is different about this card. Scaling with clock speeds definately pales in comparison to the 7970. I hardly notice a difference when I crank the speeds up, where as with the 7970 there was a definte and significant increase with a 30% OC. I almost feel like running third party software to raise clock speeds is not even worth it. I suppose this is OK since the 680 is pretty fast at stock. My other beef with clock speed is that it seems to bounce all over the place due to the nature of GPU boost. Definately irritating for the OCD overclocker.

Power Consumption--

Don't care.

Thermals--

680 runs warmer than 7970 at stock profies but is quieter by a smidge.

Noise--

Like I said, at stock profiles the card is a little bit quieter than the 7970 but noise doesn't bother me when I'm gaming since I have headphones wrapped around my head.

Outright Performance--

Definately a wash. I'm glad to have the opportunity to play with the highend cards of each manufacturer every year and the Big 2 have managed to craft nearly equal cards to time around. The 7970 is a great card that will amaze you with it's ability to exceed out of the box performance with ease giving the sensation of accomplishment with a little user tweaking.

The 680 is great out of the box and that is it. I really feel like the card was optimized to the point of perfection at the factory and it is what it is. I feel like in the long run an overclocked 7970 will be the better buy with it's higher bandwidth, mem capacity and compute performance.

In hand impression--

From a novice electronics guy's perspective... You really can tell from an engineering perspective that the 7970 is built for abuse and that the 680 seems "watered down". You really have to have first hand perspective looking at the PCB's.

Thanks for sharing. Did you try overvolting the memory? What are your maximum overclocks, what fan speed and voltage does it take to hold the max OC? Whats default VID?

1225/1650 @ 1250mv, whats load temps?

I've owned NVIDIA cards for the past 10 years, but the 7970 will be my first AMD/ATI card. Just waiting for the bundled games to hit....

very odd time to now be switching to nvidia.

amd has held the bank for buck title ever since the 4800 series.

this is the first generation where i'll probably go back to nvidia.

I like the feature set and price point of the 7970. $450 for the Sapphire card (hope it's still that price when the bundles are out) vs over $500 for the GTX 680. I'll be playing through Skyrim this summer with a LARGE amount of mods at 1440p and I think the 3gb ram will edge out the GTX 680 in performance.

You must have missed the memo. 7970's are now starting at $450AR. The 7950 is better bang/$ though if that's what you are looking for.

And Newegg just recently updated the cards to include the 3 bundled games. In for the Sapphire!

Using 3d apps and the fact that opencl performance isn't neuterd like in the Nvidia 680 makes the 7970 makes it a more attractive offer as a cheap alternative to a professional nvidia workstation gfx card.

Not to confuse the issue, but I'd be a bit concerned about the reports of coil whine with the Sapphire. I typically really like Sapphire, as they offer better bundles than the rest, but I'm not to sure about this particular model.

I was checking out Luxrender and it flies on GCN. I haven't played with it enough to get a real good feel for the program (I don't have a GCN card, BTW). C4D is my program of choice and Luxrender doesn't work with the more recent editions of it. I'm not well versed in Blender, which is where I'm forced to play with it. From the benchmarks I've seen the 680 is awful with it. About on par with a 5850 with the 7950/70 being ~3X as fast.

I haven't tried overvolting the memory. This isn't a max overclock yet. Just my next increment for long term stability. I have briefly run it at 1250/1700 with the same 1250mv and passed with flying colors.

Fan speed can be kept at the stock setting for the overclock so far but since I game with headphones on most of the time I settled with a 50% fanspeed and temps are right about 64c @ 1225/1650. My default VID is 1.17.

I also want to make note that the card can do 1160 core speed at stock voltage.

I sold both my gigabyte windforce 3x oc edition 7970s that i bought about 2 months back.

The cards had random crashes all the time in crossfire. The drivers were horrible and couldn't handle the display port functionally. Any time my monitor would go into powersave mode the videocard could never restore from that mode. It was incapable of sending a message to the monitor and os to wake up so I would have to restart my pc constantly. Shameful too, crossfire really cranked when the cards and drivers were working properly. Gaming at 2560x1600 was a treat WHEN it actually worked. Too many crashes on a perfectly stable os install just got sickening.

I'm going to see how the gtx 690 launch goes and think about picking up that or one or two 680's.

I just got a nintendo wii hooked up in my room too so i might just do some awesome lounge fest gaming from my bed for the next few months since pc gaming is relatively boring these days.

For Overclocking: in crossfire the wall was 1100mhz, anything over that would crash in any serious game. Memory could hit 1675mhz stable on both cards surprisingly.

My single card wall for overclocking was 1325mhz on the gpu at 1274mv.

The card never went over 65*c even at the overclocked level playing any game for hours at 2560x1600 maxed the FK out. If anyone is in the market for a 7970 i would recommend the gigabyte windforce edition as it's just a wonderful piece of engineering. Hardocp has a review up on it to back it up.

12.4 seems to have fixed my stability problems, finally. I might actually finally get around to overclocking some time soon!

you must've missed where he said this is the first amd card he bought in the last 10 years. at $450, the 7970 is just now priced competitively and not really priced bang for buck like the 4850/70, 5870/50, and 6970/50.

i'm not saying the 7970 is not a good buy. just that for someone that has been loyal to nvidia for 10 years and passing over the last 3 awesome amd buys for this one is just a little wierd.

it should be the other way around. you were a nvidia fan since 8800 days, switched to amd with 4800-6800 series and now are just coming back to nvidia with the expected 600 series product launches.

I agree with a lot of the sentiment here, couldn't be happier with my 7970. I've stated this before, but I've been recommending the 7950 to a lot of people lately. They dip to $380 and lower on some e-tailers, and that a price/performance ratio that can't be beat at the moment. On the flip side, I haven't seen anything in the future that can contend with my 7970 @ 1350MHz. Looks like this might be another 5870 for me.

Sounds like a pretty good card, what is the ASIC qual? Did you change the TIM? When are you going to go for that max OC run? I'm anxious to see it! :) Would like to see your max Memory OC too with some added memory voltage.

I actually haven't purchased the Sapphire card yet. Still considering options, but I would prefer non-reference cooling over a reference one since I'd like to see how far I can push the card on air.

I mean buying a 7970 in the first place when 7950 will get you there if you look at clock for clock reviews. Actually 7950 will beat GTX 680 when OCed and I've seen them as low as $369. By far best bang for buck at high end and you still get 3 free games.

I have a reference Diamond brand card, and have had it since launch.

Pluses:

-Performance is outstanding for 19x12, I can crank as much AA and details as high as possible in any game I play.

-It has a ton of OC room.

-3GB of memory means that at my resolution I am likely set for a few years.


Cons:

-NOISE.

-NOISE.

-LOUD. (when overclocked)

I will admit, I'm a bit spoiled with noise, my last two cards were Sapphire Vapor-X 5870's that you simply didn't hear, even in Crossfire. Before that I had a Sapphire Toxic Radeon 4870 that was also whisper quiet. This go around I decided to go reference for the overclocking (voltage control) potential... I'll gladly sacrifice the voltage control for a quieter card in the future. Depending on the ambient temp, somewhere between 1100-1200MHz the card simply becomes too noisey. Just my $.02

*edit - Also, the drivers seem a bit fussy at times. Games are fine, but odd things like my cursor disappearing, or half the screen not refreshing while coming out of sleep occur for me. Up to this card AMD drivers have been dead on perfect for me. Nvidia drivers in past cards have been very good, but not great. This is my first AMD based card that has any driver quirks. :/ But, I'm still on 12.3, we'll see what 12.4 does for me.

I'm enjoying mine too. Only thing is 11.12 drivers are stable for me. 12.4's make my system crash like a mother.

Have to agree with sentiments here, now with unlocked vcore, 7950s often match clockspeeds of its bigger bro, clock-for-clock you are not going to notice the difference.
