GTX 670 4 GB VRAM Usage Question

post #1 of 6
Thread Starter 
I've heard from many different people that the GTX 670 can't use all 4 GB's in the 4 GB models because of the memory bandwidth. How much VRAM can a 4 GB card actually use at most, before the bandwidth can't handle any more?

Not enough GPU muscle to use up 4gb of vram with a single card. If you use three or four GTX 670 4gb cards in sli, then it's possible to use near 4gb of vram.

From all reviews i've seen it looks like extra 2gb of vram doesnt make lots of difference, only couple fps and not in every game.

Agreed with MrTOOSHORT - it only makes difference with Sli @ 1440 and above resolutions.

It makes a ton of difference in games with high requirements. My Skyrim uses just under 3GB and it makes a world of defference. If you have AA turned on it will help as well.
