Thread Starter 
Sapphire Radeon HD6970x3 in trifire
vs
MSI Lightning Extreme GTX GeForce 580 3GBx2 in SLi

This will be for three 1600P at 1920x1200 or 2500x1600(if it runs smoothly) resolution Surround Setup. (NO i do not want 3d)

I'd pick the 580's. More RAM, and it'll be more than enough for most games on the market today.

580s, more vram
post #5 of 77
Well we really don't have a choice if it's "Nvidia Surround" 3Gb 580's, even though 2Gb should be sufficient, and three 6970's would be more powerful then two 580's, given the game scales well.

Why do you say more RAM ?, 2gbx3 = 6gb, 3gbx2 = 6 gb, am i missing something, does the third card not have all of its resources used?

No, you will ONLY have 2Gb TOTAL with the 6970's, 3Gb total for 580 Lightnings. You don't add VRAM, you go off of the card with the lowest.
