Gtx 680 Sli Benchmark
We benchmark the power of a Gtx680 Sli setup in both single and surround monitor configurations . When someone buys 2 of these cards in Sli they are without doubt going to get into overclocking, as its not your casual gamer type of card. As its easy to overclock I find a mild stable overclock of 1185mhz on the core and 6600mhz on the ram.The resolutions we shall benchmark test are 1920×1080 with a single monitor and 5760×1080 in surround, to give you a detailed review of what these cards are capable of doing in a variety of games and settings. These are reference Asus 2Gb versions, so it should be similar to what performance you would be getting with any reference 2Gb cards from most manufacturers. I have added evga backplates and hi flow air brackets to get temperatures 2-3 degrees lower.



You can check out the benchmark system my personal custom pc build here. The only difference is that the 3930k is now at 4.4ghz not 4ghz as stated.

Min : 137 fps Avg : 161.2 fps Max : 186 fps

1920×1080 High Specs
Min : 116 fps Avg : 139.1 fps Max : 161 fps

1920×1080 Ultra Specs (Ubersampling On)
Min : 57 fps Avg : 67.5 fps Max : 72 fps
We see that the Gtx680 sli configuration has no trouble running the game @ 1920×1080. The game was very smooth even with ultra specs and ubersampling on.
Gtx680 Sli Witcher 2 5760×1080 Surround Benchmarks
5760×1080 Surround Low Specs
Min : 77 fps Avg : 81.7 fps Max : 88 fps

5760×1080 Medium Specs
Min : 57 fps Avg : 63.9 fps Max : 68 fps

5760×1080 High Specs
Min : 44fps Avg : 51.4 fps Max : 57 fps

5760×1080 Surround Ultra Specs (Ubersampling On)
Min : 21 fps Avg : 24.5 fps Max : 28 fps
All settings seem to play smoothly at this huge resolution, other than the ultra specs because of the ubersampling (Maximum antialiasing). With ubersampling on, other than objects shining more I felt that it didn’t give enough in graphics quality to overcome the framerates being cut in half. We see that even with 2gb memory there seems to be no vram bottleneck and no huge fps drops, the Nvidia 600 series seems to utilize the memory well in combination with the well configured Witcher 2 texture allocation.

Bf3 680 Sli Benchmarks
You all know Battlefield 3, I tested the cards on a single player campaign in the parking lot, with rockets flying around and alot of enemy gunfire. I was using both sniper and normal shooting in the benchmarks. We will go straight to the Surround tests as it played the 1920×1080 ultra settings (4xAA) at over 75+ fps constantly with no huge frame rate drops.
Depth of field of 70 (default) on all Benchmarks

5760×1080 Low settings preset
Min : 94 fps Avg : 111 fps Max : 195 fps

5760×1080 Medium settings preset
Min : 83 fps Avg : 92 fps Max : 105 fps

5760×1080 High settings preset
Min : 67 fps Avg : 76.9 fps Max : 88 fps

5760×1080 Ultra settings (4xAA) preset
Min : 48 fps Avg : 54.3 fps Max : 65 fps
As you can see every setting runs pretty well on the Gtx680 Sli configuration even with ultra settings in singleplayer mode . If you play online in multiplayer mode high settings will be the perfect fit to run it even smoother.

I take a run through the first episode in open terrain killing the enemies to get the 2gb memory bandwidth working.

1920×1080 Hardcore Settings
Min : 92 fps Avg : 114.2 fps Max : 135 fps

5760×1080 Hardcore Settings
Min : 57 fps Avg : 67.50 fps Max : 91 fps
Conclusion
In general I am very happy to say that my money wasn’t wasted. Alot of criticism has been done against Nvidia about its 600 series release but it proves exactly the opposite especially in Sli.
