Not them, but perhaps they're sales.
Because lets face it, a 7900 GT with a GTX cooler could potentially OC to exactly GTX speeds at a much cheaper price.

AFAIK the memory used for 7900 GT's is 1.4ns so it's unlikely they'll come close to OC'ing as good as a GTX that has 1.1ns memory and probably higher voltage as well.
I'm sure they could, because I've already seen an XFX 7900 GT XXX Extreme version that is factory OC'd to 560/1650 with the stock cooler. thats already faster memory then the stock 7900 GTX memory speeds.
Now imagine what it could do with an aftermarket cooler?
I'm guessing 600/1700.
Maybe even more on the core, who knows.
You guys are still acting like children. Fact is, both cards shimmer, it's more noticeable on NV cards, and everyone now knows (whether they knew before or not). As someone else said, the bottom line is that it's pathetic that someone spends $500, be it for ATI or NV, and ends up with this kind of crap.
My dad can beat up your dad and my bike is cooler than yours. Let's keep arguing about insignificant things, 'cause I'm sure this debate will end up on the nightly news along with war, death, poverty, famine and rape. It's so important!

The factory OC'd cards could be running on higher voltages. I really doubt a standard GT will hit 1700 mhz on the memory if it has 1.4ns. When you get your GT's let us know though. BTW if you have the balls, here's a voltmod for the 7900: http://www.vr-zone.com/?i=3330
So can anyone give me a follow up on what type of ram the 7900 GT uses?
Any close up pics?
1.2ns ram or 1.4ns?

I believe 1.4ns = 700 mhz so you should have some OC room though 1700 mhz seems like a big stretch unless you vmod it like crazy. Just FYI I can barely get above 1700 mhz with 1.1ns ram.

Joker, can we keep the "could be's" out of this conversation and lets stick to what we can see? Trying to keep assumptions down to a bare minimum if possible. I have seen factory overclocked 7900GT's at 600/1650 which is very impressive for a warrantied card. At these speeds, the 7900GT's are knocking at the performance door of the 7900GTX which default is 650/1600.
I have not seen any mention of pumped up voltages on those cards. Yet.

Factory OC'd is very different than buying a standard GT and expecting the same OC out of the memory. Of course there is going to be speculation if he's buying a standard GT and wondering about how far it will OC.

YMMV of course, but its looking promising if so many vendors are offering this highly clocked cards at first release.
And, it may just be worth it to buy the factory o/c'd versions for damn near 7900GTX performance for 350.00 bucks. You're still paying at least 150.00 bucks less for essentially the same card. (performance wise).

Well it's no different than the KO editions were when the 7800 first launched. They had very little OC room left in them using a standard bios (the one w/delta clocks intact.) I'm not saying he won't be able to match the factory OC'd GT's but that there is always a possiblity those factory OC'd cards have something different about them:
1. speed binned modules.
2. relaxed timings.
3. higher voltages.
I don't think factory OC'd ones are worth the extra $50, it would be better to just add in a bit more extra cash and go for a GTX which would give him a lot more OC headroom.
No way am I messing with the actual physical characteristics of the board, I dont really want to use any voltmodding either.
I'll see what i can get on stock volts but with aftermarket coolers.
3DGuru managed 545/1568 OC on stock cooling and voltage. Remember, on stock cooling, the rams are'nt even cooled by a heatsink AT ALL!!
So I doubt the 1.4ns ram makes that much of a negative impact.
I reckon 1600mhz memory might be easily do'able with aftermarket cooling.

Ah my bad, ok $50 + $25 for the cooler is still a lot of extra cash vs. just getting a GTX for ~$100+ more than the OC'd ones and getting a much better stock cooler w/it and a lot greater OC headroom.

When you get your cards, keep your core stock and then OC your memory and benchmark it against your card stock to see if you get a big increase.
Perhaps, but in the UK the 7900 GTX is roughly £400.
I paid £223 each for my 7900 GT's.
Thats nearly half the price of a 7900 GTX, so the choice was a no brainer.
SLI FTW!

a personal issue perhaps, but damn it's annoying
Its present with both vendors off in the distance if you look for it, if it is substantially worse with the 7000 series i wouldnt know, havent seen one in action yet.
I would like to see a world with no LOD falloff at all, then you dont have to worry about bands of crap filtering, its all the same.
A little update.
Just realised firing squad also managed a high 7900 GT OC on stock cooling and voltage. They did 550/1580.
The OC also did far better for performance then their OC with the 7900 GTX.
See results here.

Cant wait to see how this kind of OC run in SLI would do.

shimmering is present on both sides, more so on NV
and i think LCD's just compound the issue even more

that's all i'm really playing atm. I just tend to ignore it after i get drunk, so that helps i suppose
CS:s shimmers like crazy....even on my brothers 9500pro and a CRT.
