Performance in Simulators
There is no point in overclocking your GTX 570 for this game because the game itself has rather low system requirements and the difference between the average and bottom speed is very small here. There is a performance gain, of course, and the Gigabyte card is about 17% faster than the reference one at 2560x1600, for example. But you can hardly feel the difference in practice.

StarCraft II: Wings of Liberty
Again, overclocking your GeForce GTX 570 doesn’t make sense if you play at resolutions up to 1920x1080, but it can improve the bottom speed in the Ultra HD mode. Your card doesn’t have to set new overclocking records for that, by the way. The modest overclocking results of our ASUS are quite sufficient.
Total War: Shogun 2
The latest patch allows using FSAA without disabling special effects.
The bottom speed of the GeForce GTX 570s does not grow up as much as to bring any tangible benefits. The good news is that a well-overclocked GeForce GTX 570 can beat a regular and more expensive GeForce GTX 580 in this real-time strategy.
