Following on from my GTX680 review and the positive opinion I had of the GTX680 as a single GPU and the performance it offered. I’ll now be showing you the results of my testing using two GTX680s in SLI, what I can say straight off the bat is that it is by far the most powerful GPU configuration I have ever had. Without further ado, I’ll get into the review; I’ll try to keep it short and sweet, showing the frame rates and also the average FPS scaling over a single GPU.
I5 2500k @ 4.6GHZ
16GB @ 1600MHZ CL9 Memory
Asus Maximus IV Extreme P67
120GB Crucial M4
2TB Samsung F4
Palit Nvidia GTX680 x2 SLI
850W XFX Pro Series PSU
Notes: I’m using the first official Nvidia GTX680 drivers, all tests are at 1920x1080 using the settings specified in each different test and any anomalies that come out in testing I’ll discuss and review accordingly
I was initially happily surprised with the single GTX680 (as per my review here) in terms of how quiet the card was when it was running in a single GPU configuration, I’m pleased to state that with a single space gap between the cards, running them in SLI was similar noise wise, although the fans had ramped up slightly higher and as an offset with more heat being in the case, the cards were a tad hotter.
Without any further stalling, let's get onto the benchmarks. As with a setup of this magnitude, you’re going to want the figures.
