Should I switch from 2 GTX 580 SLI to a single GTX 680?

You can see my system specs below. I'm running two EVGA GTX 580s 1.5gb in SLI right now. Slightly OC'd I smoke the only game I play (BF3). On highest settings I average ~80 FPS... and hit 100+ often. My max temps are 75/73 running my fans at 95%.

I'm thinking of ditching these for a single GTX680. Would I see a big drop in performance? I heard you can't tweak the voltage on the 680... is that true? If so, does it OC well? I play BF3 at 1920x1080. I _may_ go up in res at some point so should I go 4gb card or is the 2gb plenty?

If I ebay my 580s it should only run me $150 to upgrade. Heck, the power savings might pay for itself pretty quick.

Thanks for the info!

I forgot to mention... I use this PC for HD video editing also. I wonder if the 4gb will help rendering too? Or is that mostly CPU speed / system ram?

What video editing software do you use?

The 680 is not as fast as two 580s even if overclocking is considered (although it can overclock well). The 680 is only marginally better than the 670 anyway, so it's not exactly an optimal buy at all anymore. It would be quite the performance down-grade, but it would cut down on power consumption greatly. The 670/680 don't have a wide enough memory bus for them to take advantage of more than 2GB of memory very well. You'd probably be better off with a Radeon 7950 or 7970 and overclocking, but again, a single 7950 or 7970 won't be able to beat two 580s.

I would recommend staying with the 2 580s as they are faster than a single 680 by far, save the money or put it into a nice 256 gig or larger ssd which would really show some nice performance boost in your pc in daily use.

It's hard to say because I don't use those programs, but I'm not sure if the Kepler cards would be an upgrade or a crippling downgrade for your video editing. Depending on the type of math that those programs use, the Kepler card's could show huge weakness or huge strength. Their dual-precision performance is much lower than that of the 580, but their single precision performance is much higher. I'm also not sure if AMD cards would be a better option because in programs that can well-utilize more OpenCL and Direct 3D, the Radeon 7950 and 7970 can often be between 50% or so and over five times faster than the GTX 670 and the GTX 680 because they have much more of a compute performance focus than the consumer Kepler cards do.

nVidia's next arch.
your set-up now is good enough to skip the new released Kepler (GTX 6 series).
at least wait for the GTX 7 series to come out and see if the proper enhancements are made with those.
but you amigo do not need to upgrade just yet unless you just wanna spend money right now.

for gaming the GTX 6 series is King for gamin but for computing task it kinda sucks.
maybe the GTX 7 series will work on that, not sure yet.
but the new arch (GTX 8) Maxwell (we believe) will be ALL THAT I assure you.

thanks, I gave you credit on the HD 7850 vs GTX 560 Ti thread.
your right about the 7850 beating the 560 Ti in performance..

cheers.
