2x 6990 or 3x GTX 580 3gb for 7680x1600 - Page 2

post #11 of 34
3x 30" Dell monitors at $1200 a pop. Dude, go for the triple GTX580 3GB cards. You'll NEED that extra VRAM to power those displays period.

MPC used 3x GTX580 1.5GB's in this years Dream Machine, and it apparently played their 3x NEC PA301W ($2300 ea) very nicely... However, to be on the safe side, 3x GTX580 3GB's would be the way to go!

Hmm, may not be able to go with 3 way, none of the motherboards can support 3x 2 slot GPU's and a 1x sound card.

Then go 2 way. That should still be more than ample power to push that kind of resolution. You might have to sacrifice some visual quality on RARE occasions, but that's about it.

And to be honest, Tri SLI, Quad SLI, TriFire, and Quad Fire all have pretty bad scaling anyway. The more GPU's you add in, the worse scaling you're going to get.

6990 + 6970 Trifire is the way I'd go. That will easily get you buy until the new cards are released. You could probably sell and upgrade again without losing too much.

If you go 2 way 580's then you might as well get 6990+6970 Tri-Fire. I have heard good things with Tri-Fire scaling.

Isn't there a 4 or even 5gb version of the 6990?

EDIT: newegg doesn't seem to carry any however there are 4Gb 6990's that you can find through google.

While that is a true point, he's still going to end up getting VRAM capped with 2GB of VRAM. Keep in mind, he's on triple 2560x1600 screens.

I could be wrong, but I honestly believe that the 3GB cards would be the way to go with such a high resolution.

A HD6990 is 4GB, yes. But its 2 GPU's, so its 2GB per GPU.

Max AA and AF are going to choke 2 way SLI at 7680x1600 in BC2 and with a build like that...it's going to be really disappointing when it happens.

You have to go 3 way SLI or Quadfire. Quadfire scaling Tri SLI scaling Keep in mind those threads aren't very recent.
