SLI, performance boost?

post #1 of 9
Thread Starter 
Just wondered if anyone out there would know what kind of performance boost would I get if I sli out my Evga Geforce GTX 660 FTW Signature 2 3gb 192-bit GPU. Been looking online still cannot get a straight answer, what would 2 of these cards be like Sli'd out just wanting a straight up review, get just bits and pieces on searches nothing in black and white, if you get me. So please, a big thanks to all that reply. thumb.gif

This is the best I could find:
http://www.behardware.com/articles/876-1/review-nvidia-geforce-gtx-660-asus-directcu-ii-top-and-sli.html (actually a really good one)

It will definitely give a significant performance increase. The only issue I see with SLI (what I've observed on mine at least) is that there is plenty of stuttering in some games to be had. Other than that, the extra card is totally worth the performance gains in comparison to the latency (stuttering).

You'd get performance a bit above the GTX 680.

I'd go with this review a bit more over that one linked above. http://www.youtube.com/watch?v=Iy5478lBais

Not necessarily. I looked at the section for Battlefield 3, and while they don't give specific settings, it seemed pretty accurate compared to my benchmarking experience. Don't get me wrong, it could be wrong. But it doesn't seem that off.

Here, have another. Some of these are actually hard to find.

Review: nVidia GeForce GTX 660 & SLI

i just PM'd a guy that had a 660 SLI setup before he upgraded to 770 SLI. maybe he'll have the time to pop in and answer any questions you got. thumb.gif

Typically 80-90%, barring cases of SLI incompatibility with one game or another, or a bad driver issue.

So basically, whatever you get now, doubled, minus a little bit.
