I'm going for a 3 monitor set-up and like many I'm waiting to see how the futur Nvidia GPUs will perform before making my mind. I'm going for either CF hd7970 or sli gtx680 so its 6GB vs 4GB. As for the games of today I'm pretty sure 4gb would be enough to run anything on ultra setting 4AA but I fear about the futur.
Anyone else think that 2gb on such a powerfull GPU might prevent the card to reach its full potential ?
I know a guy who plays BF3 at 1200x5760 high (With a Radeon HD 7970 45fps give or take) and at Ultra settings BF3 needs 1.25GB of VRAM with a single 1080p setup. The benchmarks will tell for sure which card is better at 3 x monitors but so far the math is not on Nvidia's side.
