Does it make sense to SLI 2gb 680s?

post #1 of 12
Thread Starter 
Wouldn't VRAM usage be a problem? I'm planning to step up to triple monitors soon, and I was going to add another 680 when I come back from vacation in July.

Will 2GB VRAM be a problem at 5760x1080? Should be fine at 1920x1080 for sure, right?

Yes 2gb of VRAM would be a problem for a surround setup. You'd want at least 3gb. But for 1080p it's enough for a while at least. I wouldn't do surround with 2gb 680s though. To get a descent experience you'd want at least a couple 7950/7970s, a 7990, or preferably SLI 780s or Titans.

Is surround really that demanding? Should I even bother doing SLI then?

Games like Crysis 3, Arkham City, Assassin's creed 3, BF3, etc...

So will I max out VRAM usage before GPU usage?

AC3 and BAC should be ok if you turn AA down, but Crysis 3 and BF3 will eat that 2GB alive......BF3 multiplayer is a monster, so both gpu and vram will be brought to their knees

Thanks for the help. Would it be wiser to wait for Maxwell before doing SLI, and then going surround?

The way you've laid it out for me, is that SLI 2gb 680s would be essentially useless for surround, and overkill for a single monitor. Is this correct?

I just jumped to surround with sli 670's (2gb)

modded skyrim (as expected) easily eats through it

BF3 multiplayer I turned down AA (I think post processing AA on low, rest off), but it was still hovering around 1960mb of vram usage. Thankfully with the art-style of BF3, it's hard to tell texture quality difference between high and ultra, so I turned it down to high and I'm at a comfortable ~1700mb

still tempted to go with a Titan to never worry about vram usage again for a few years though

You should try it out before you spend money on a 3gb card. You can all ways return the card.
