Ok so here what happened, i bought a video card awhile ago with the intention of buying the exact same one and preforming cross fire, But i waited to long and now the video card is no longer in production, and the only place i can find it is on some creepy website where i dont want to spend $300+

So i want to just buy a new video card. but i was wondering if it is better to get 2 video cards and preform cross-fire, or should i buy just one video card

i was thinking so the specs along the lines of this: 2x 1Gb DDR5 800 stream prosessing units or 1GB DDR5 1600stream prosessing units.

also my case:
and PSU:
also my case is loaded with high powered Fans and is very cool inside.
if you find a video card that you think i might want, the budget is $250-$300

please ask if you need any more spec or questions.
Thank you

Same issue, lemme guess Sapphire hd5850 2gb. Got a 1gb of Ebay on the way to see what it does. 5870's are too long for my storm case as I am sure it is for yours.
However I question the upgrade @ all as the single card runs Crysis 2 on Extreme settings @ 60hz no problem. Only time it drops is the loading screen which isnt sending that many frames so go figure.
Second issue I have is card spacing, all cards are now 2-slots. Why then are PCIe slots spaced every other? If it was every 3rd it would be perfect, or if the cards were 1 1/2-slot it would work, dont the designers of these things build PC's any more.
Third issue I have is games are getting to the point that they are ported from console to PC, where it used to be the other way around. I have all 3 consoles and the 3ds, so why not just play it on the console if it was made for the console? No controller configs to deal with or WSAD, etc.. The ~console is also dissappearing, so almost no benefit to getting the PC version anymore. Its sad really.

At that price you are better CF 2 6850, their performance in pair are the same as 2 5850 due to scaling improvement. You can have the 2 for around 340$ for new. I f you check for a bargain, you could even find a cheaper price.

had crossfire 6870s drivers worked like ***, the problems were consistent across several drivers and games; low minimum fps and sporadic micro-stutter not to mention flickering. I could go on all day but personally I'd go for a single card solution such as a 6950/70 or gtx 570

Ok I think were getting somewhere now thanks.
heres my full system specs.

CPU:AMD PhenomII X6 1090T running OC at 3.7GHz
MB:Asus M4A89TD PRO USB3 (chipset-AMD 890FX)
RAM:4GBs DDR3 1600

Please tell me if I missed anything.

I have one other small question, which i think i have an idea from what jjb8675309 said, but the question is which is more efficient 2 video cards connected with cross fire or 1 super big crazy fast video card. but the info your giving me is also helping.

thanks for the quick replys

personally I prefer a single powerful card
April 25, 2011 2:43:28 PM

oh i forgot about my monitor is: Res- 1920x1080 60Hz 23"

im not trying to be rude, i just dont want to spend $300 with out doing a crazy amount of research, but if i have 2 video cards with the specs. of 1GB with 800 stream prosessing units, will it run better than my 1GB 1600 stream prosessing unit video card?
or is it a matter of heat and space in the case, or just that when video cards run in cross fire they are not a effecient as 1 big one.

again sorry for the questions, but thanks for the answers

what cards specifically are you talking about, crossfire drivers work like ass, you are much better with a single gpu. personally I went from 6870 crossfire to a single gtx 570 and I'm thrilled

I was thinking of a 6000 GPU but it sounds like you were having some problems with them.

they are fine in a single card config, imo, but amd treats their crossfire customers like a minority. The best bang for your buck is probly the 6950 2 gig flashed to a 6970 or a gtx 570

ok so im looking at this one: (newegg num)Item#: N82E16814102928

Im really looking for an UP-GRADE cause right now im running an Radeon HD 5870 1GB DDR5 with 1600 stream prosessing units but the one i mentioned only has 1408 Stream Processing Units, but is that not enough of a difference for my preformance to slow noticeably?

1920x1080 on a 23" screen? Why are you even looking? Marketing loves you.
