3 580's 3gb or 2 6990's - Page 4

post #31 of 135
i'd have to go with the 3x580 3gb... they are technically more powerful than 6990's in quadfire... i think, i'm not a 100% sure.

i think 2x6990s would run hotter than 3x580s.... that i am pretty sure, but again not a 100%

and most importantly they will make less noise

if you are going to use water cooling on all that stuff then again 580's OCed will leave dust on 2 6990's... (even iof they are opened to 6970 clocks...)


also I heared the 6990 have the same micro sttuting problems as the 5970 head...

Not quite. Resolutions even at 7k x 1600 or 2560 x 4800 still benefit from SSAA or MSAA

Also, a 1600 AA doesn't do much at all.
Huh? 1440p is just the 16:9 equivalent of 2560x1600. It's like comparing 1920x1080 to 1920x1200.

You may not need as much as you would at 1080p, but jagged edges are still very apparent without AA at 1440 and 1600. Personally I prefer at least 4x.

How about: HD 6990 + HD 6970 + GTX 460 PhysX

Great choice, 3x GTX 580s should be better especially once OC'ed

Agreed. Personally, I'd wait for the newer 3GB models though. They're supposed to be closer to $500 retail.
post #38 of 135
3x 3GB GTX580s for the following reasons:

1. Better overclocking headroom because you have more surface area and volume to dissipate the heat. If you are water cooling, Fermi seems to go further than does Cypress.

2. 3GB frame buffer is 50% larger than that of the 6990s, the only reason that the 6970s could be considered the equal of the GTX580 at higher resolutions was to the latter's lack of VRAM. The Fermi cores have thusfar been far more computer heavy and limited by their frame buffers.

3. You are asking in the Nvidia section of OCN... there is obligatory fanboyism.

3 580s SLI or 2 6990s? Did Crysis 5 come out and I am not aware? Both set ups are pretty over kill.
