Well, the 690 is $1000, whereas the 7970 is like $400-$500.

The GTX690 is faster, but it is also a dual-GPU card, meaning it runs in SLI. SLI has its issues, namely microstuttering and power requirements.

The 7970 in only a single GPU and uses less power. It will also be better at video rendering and photoshop work as well as gaming. The new GTX6xx series cards are not that great for that purpose.

It is easier to explain the difference between the cards in the context of your computer. What computer do you have, including the power supply?

well, 3960k OC 4.4, H70 CPU cooler, Asus IV formula rampage, 2x gtx 680, 32 gb of ram, cooler master 1200w 80+ gold, 2x 1TB WD HDD; 2x 512 gb intel SSD, Asus 27'' inch 3D vision monitor and Corsair 800D Full tower gaming case

Well, does it stay at 60fps? Or does it dip. There is nothing faster right now than 2 680's.


3 GTX 680s ;) 



Your 2 GTX 680's are a GTX 690. So its a waste. Also check if you have v-sync on. That will cap you right at 60 FPS.

someone that has a computer that sik, should know better. not to mention 'starcraft' is like 45 years old, and the second one is not that demanding either.

Best solution

Perhaps the OP is considering 2 gtx690s in sli(not the best idea)? They could consider 3
gtx680s(better scaling with 3 faster cards versus 4 gpu), Or they could sell the gtx690
for close to what they paid for it(maybe more) and get 3 hd7970 for less coin and overclock
them past 7970ghz ed.(faster than gtx680). Since the OP has a 3D display, they are
shooting for 120fps or better. Checking to make sure vsync is off is a bad idea(though
tahiti doesn't have adaptive vsync, there are ways to force vsync and triple buffering at
the same time to even better effect).

Not really sure why you'd want to run starcraft in 3d but whatever(like 2d isometric in 3d).

I take it back, checking whether vsync is on or off is a good idea. If you are running over
60fps but the monitor refresh is 120 and you don't get near that, vsync will drop your
fps to half the refresh or 60fps. Or, since you are using nvidia cards, maybe you are
using adaptive vsync? I am guessing mousemonkey will close this thread soon, but if
you want to chat about this with one or more of us after that you can PM us by clicking
