Crossfire ATI HD 5770 or 5850?

Best bang for the buck but not lossing worthwhile performance from Crossfire; 2x 5770 or 2x 5850?

I just don't know if two 5770 are worth it ..maybe not as powerfull as a single 5870, I don't know. I'm obviously looking for bang for the buck and not spending a cent more than I need to.

Best bang for the bug depends on what you are going to be doing. I'd suggest a single 5850 before you consider crossfire options. I'm almost certain 2 x 5850 is not going to be best bang for the buck. 2 x 5770 vs a single 5850 is a harder question.
The 5770s will in almost all circumstances be faster, but they are more likely to have issues and possibly lower minimum frame rates (sometimes this is due to the first problem). If you're getting crossfire no matter what I'd say 2 x 5770s is better since you get more (percentage wise) out of the second card and it's much cheaper. Scaling is about 80% though it varies quite a bit by game from what I've seen. Scaling is less than that with the 5850s though ultimately they would be faster.

5850. The 5770s 128-bit memory bandwidth will come into play at higher resolutions and the 5850 is much faster than the 5770 in most cases.
 
HD 5830 in two weeks. I just got a glimpse of that news. I'll wait on 5830 reviews then. Yeah I agree with the 5850 over the 5770's unless I'm in a dead rush for Crossfire.
 
No it doesn't. Two 5770's in Xfire kicks the crap out of the 5850 and is even faster then the 5870
yeah in the majority of cases that is true. there will be a few games that will still have a fairly low minimum speed in some scenarios though. If the 5770 cards were about 30 bucks cheaper I might would give crossfire a chance.

True. It does. But with the single, more powerful card, minimum framerates are arguably assumed to be higher. In high resolution or increased AA situations, memory bandwidth plays a major role in overall performance if the SP's can delever enough information. In saying this the 5850 must have higher minimum framerates in situations where it matters most.
 
We are to expect the HD 5830 to come in at about $220.00 right? Is it supposed to have 256 or 128 bit memory interface? I'm guessing 256 since it is a 58xx.

I guess I can wait two weeks... but maybe the 5770 x 2 is the best price point right now. I have almost ignored SLI and Crossfire since it came out so I don't know how it works at all.

128bit memory interface going to hamper things much?

My doctor usually says "Lets handle one thing at a time" right about now. Sorry, lol

It seems the 5830 is going to end up being $230 which is too expensive for how much it's supposed to perform.

yeah the 5830 will certainly not be 128bit. what does the rest of your system look like and what res will you be playing at?
 
Yes but we can all find it for at least 8% off and free shipping I'll wager. $211.00 ...not too bad there.

ASUS P5E Deluxe
Mushkin XP2-8000 Redline 2x2Gb (and another 2x2Gb of that stuff if needed) or Mushkin XP2-6400 2x2Gb (996561) or 2x2Gb of Buffalo Firestix (also D9 stuff) ..opstions
Thermalright cooler and Arctic Cooling fans (why doesn't any maker label thier heatsinks with freakin model numbers?) (..Arctic Cooling fans were a good investment--quiet)
Lian Li server case (black stealth look is nice)
Auzentech Prelude (matured to a nice card)
PC Power & Cooling 1k Watt (the copper one)
two Western Digital RE2 drives in RAID 0 500 + 500Gb (not very fast really)
Rosewill angled black SATA cables...
old Pioneer DVD burner that doesn't get used.
one NVIDIA 8800GT with a Thermalright kit on it and another Arctic Cooling fan

oh and an Intel E8500 (4GHz OC)

Well ..Jesus, I don't know the sale prices yet. Hahaha

There will be sales on it and deals. I can get 8% off through Bing or my banks MemberShopping. Free shipping happens regularly.

is there a cpu and monitor resolution you will be gaming at in there? lol. also are you planning to power two computers because you want even come remotely close to needing even half of what that 1000watt power is needed for? even an i7 cpu and 5770 crossfire setup would only pull around 300 watts.

Yeah I bought that when I thought the trend was going to be more and more power usage. It looked that way for a while so I thought I'd get one that will have me covered. Not even sure why they make those for the mainstream audience. Its a great PSU but it is about 5 years old now. I hope it lasts. I still have PC Power & Cooling PSu's from 2001 that work. 300watt things ..I wouldn't try and use them on anything modern though.

I've got a few other PC Power & Cooling PSU's also. 400 and 600 x 2. The 1K has all the connectors I need.

E8500 btw.

1080p gaming on the LCD tv.

I can get HD 5850's for $276.00 each with shipping paid and no tax right now. I Won'e be paying close to that for my second or I won't buy a second, unfortunatly.

a single 5850 is good for 1920x1080 especially when you overclock it. I would probably go with a quad core cpu before I would get something like 5850 crossfire though. I am running into a few games where my cpu is causing the bottleneck and thats just with a much slower gtx260. what I mean by that is games like Red Faction Guerrilla, Ghostbusters, and GTA 4 are causing just as much grief for my cpu as STALKER Clear Sky and Crysis are for my gpu.

Toyota what speed is your E8500 clocked at?
 
Ah okay. I take it those games multithreaded. Are they? What is the quadcore equivelant of our CPU or better? I want to stay in my 775 socket and DDR2 a while longer.

I'll go a single 5850 maybe but not sure there is enough multicore support in games yet. I'll have to look into it. I'm pretty sure the 5850 crossfire will bottleneck even a quadcore socket 775 but that is expected until I upgrade.

What CPU you planning to get?

3.8 and it still tanks in spots in those games. at stock 3.16 GTA 4 was too sluggish in many spots with the settings I was using. overclocking the cpu gave me 6 more fps in the benchmark and helped quite a bit though. Red Faction is demanding when the shit hits the fan and all that physics is getting done on the cpu. Ghostbusters will use 75-80% of a fast quad so there will be times that no dual core will keep the framerate out of the 20s with highest settings. besides those 3 games everything else I play is pretty much limited by the gpu if there is a limitation at all.

well I cant really decide at the moment but GTA 4 is way faster on an i5/i7 than a Core 2 Quad. I dont really want to change mobo/cpu/ram at the moment though because the overall cost is too hard to justify for just a few games. at the same time the Q9550 is not a really good deal at over 250 bucks either. I got through Ghostbusters already and the main story in Red Faction so I may just wait until I see a better quad core solution before going back to GTA 4. I was hoping to get a 32nm quad but it looks like those will only be Xeon cpus.

I've played GTA 4 on my current system and I can't say it was lagging or slow. No jitters or anything. I'm at 4GHz and run it on that 8800GT so... not sure, sounds odd it plays that poorly for you. I have seen games lately eating past 4GB RAM when i had all of my Radline installed (8GB). I just did a random check and the game was gobbling up RAM like crazy. It was past 4Gb total system usage. Don't recal what game. Maybe it's RAM??

well it doesnt really play poorly but I cant run the settings at what I want to run them at though. I am not too far from maxing out the game but my cpu that will have me in mid to low 20s for minimums if I start turning things up. with a few things turned down it is fine at 3.8 and will usually not drop below 30fps too often.
