Something like that.
As it stands now, even at 5760x1200, the SLI 680 2GB cards beat out the 3GB 7970 XF in terms of max playable settings in everything that [H]ardOCP tested them on ...
I mean, if you got the bucks to throw around, AWESOME, man. I'm envious. And as long as the 4gb versions aren't lot more expensive than the 2's, why the hell not get 'em, right? I'm just saying ... you're going to be really hard-pressed to create a scenario where you actually NEED the 4GB version without the following:
a) having a HUGE resolution, and
b) having two (or more) of them in SLI
At least not with any game that's out there presently
^this! I game on the 2gb 680s cards at 5760x1080 and I couldn't agree with this more...
If you do happen to encounter a situation where you're getting close, or you think you're maxing it and it's lowering your fps, then just turn AA down a notch... Better yet, use post processing AA, instead.
1. Are there any disadvantages to adding a second card? Can it be easily disabled in games where it's not supported/needed? Microstuttering?
A tad bit louder. More heat output (prepare for a small space heater, hehe). More power consumption. Some games may not have SLI support (if you're running really obscure games, possibly). Yes, SLI can be disabled. I haven't noticed any microstutter with my SLI 680s. If you have any issues, you've added another component to troubleshoot, just sayin'.
2. Will the 2GB of VRAM possibly hold me back? Will run Skyrim a lot, with mods, so I'm thinking it might...
No, not of if you do it right. Just be smart with your mods and AA. Don't go loading 4k mods on things like bugs and you'll be fine. Run a texture optimizer when you can, and on things that don't have to be super-high res... lol In short, just use some common sense about what you're loading high res packs for, and pay attention to what is _in_ your data folder. This is all stuff one should be doing already.Edited by svthomas - 5/4/12 at 9:56am
