Currently have an EVGA GTX 680 SC. Thinking of going SLI. Any warnings?

Main warning is its likely your VRAM will become a bottleneck to your performance. Not a massive issue to most, but can be compounded by using a very high resolution or high res texture mods etc. Some newer games (BF4? ) already requiring more than 2gb of VRAM at high settings.


My SLI 680's still gave me 60-74 fps on ultra at 1080p on BF4 in beta. I still call BS on those requirements.


VRAM doesn't really limit max framerate; you just get annoying stuttering when you go over 100% usage. You may well be right about BF4, though; I haven't tried it.

If the game really needed more than 2GB, he'd get heavy stuttering that makes the game nearly unplayable. Worst case scenario is CTD.

Yep, I think that is consistent with what I just said.

Be careful if you go over your cards maximum VRAM however, you will get stuttering, and eventually a crash.

Point is, he'd definitely notice if the 2GB VRAM caused a bottleneck. He's not wrong about the system requirements being BS.

As for resolutions higher than 1080p, using up more than 2GB of VRAM is not something we haven't seen before.
