In Futuremark 3DMark11 with the performance preset we found the GeForce GTX 680 had an overall score of P9767. When overclocked to the max we hit P11000! This is a performance gain of ~12.6% and enough to put the GeForce GTX 680 ahead of the GeForce GTX 590 and even the AMD Radeon HD 6990 OC! This isn’t a real game though, so let’s take a look at some real game titles.
In the game title Just Cause 2 we found the that the overclock helped boost the frame rate significantly! At 1280×1024 we saw a 6.6% performance improvement, followed by 8.0% at 1920×1080 and 11.7% at 2560×1600. Not a bad performance jump for free!
In Metro 2033 we saw a 6-8% performance improvement thanks to overclocking!
The final game title that we benchmarked the GeForce GTX680 overclocked on was Battlefield 3 and we saw a 9.4% performance improvement at 2560×1600 thanks to overclocking and was able to play on this Ultra HD screen resolution at above 50 FPS on average. We saw a solid 8-11% performance increase thanks to our overclock in BF3.
