3 580's 3gb or 2 6990's

post #1 of 135
Thread Starter 
Which one?

I'm looking into dropping a quite large sum of money on a new build and was wondering which would be better. I was considering 2 590's but there having vrm issues.

Forgot to mention they will be under water.

UPDATE: UD7 arrived. I'll be ordering the 2600K later this evening after I make a deposit.

i would say 6990's

essentialy they have better scaling and also more room in your case means cooler/quieter with only 2 cards (which of course would count for 4 6950/70's vs 3 580's)

You will have more VRAM with the 3GB 580s(3GB useable compared the 6990s 2GB), but you shouldn't need more than 2. I'd get two 6990s as they are more powerful.

3 580's for sure

they will overclock much better and quad scaling is always worse then tri SLI/CF scaling

the 580 will make more hit but in total they should be cooler...


edit
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...

um, two 6990's for sure. price comparison alone isn't even close. scaling is better as well. and yeah, don't get 590's. noise level isn't an issue as op stated they will be under water.

2x 6990's = $1400

3x 3gb 580's = ~$1900

You're not running it on a 1055 are you? 6990's are very hot right now.

I perceive that money (''quite large sum of money''), heat and noise (''under water'') are not going to be an issue.

And I note that you will run 3x1080p monitors. Because of this ultra resolution, I suggest three GTX580 3GB models for the 3GB VRAM. It will allow you to go higher in AA.

Right now, Palit, Gainward, Inno3D, EVGA and Zotac have released (or will very soon release) 3GB models.

i would hope so or at least a 2500k
anything less than that would bottleneck eigther of his stated options.

3GB 580s, easily stronger at higher resolution than the 6990 and like windfire said, crank AA up.
