Performance in Simulators
The PowerColor is also good in this Formula 1 simulator. It delivers a higher speed than the GeForce GTX 560 Ti and is close to the more expensive GeForce GTX 570.
Performance in Strategies
StarCraft II: Wings of Liberty
StarCraft II is perhaps the only game so far where our overclocking is rewarding as it improves the speed of the PowerColor HD6950 1GB at 2560x1600, making the game more comfortable to play at that resolution. Overall, the Radeon HD 6950 1GB is almost as good as the GeForce GTX 570.
Total War: Shogun 2
The game engine makes us choose between FSAA and the full selection of special effects. We prefer to enable all of the special effects at the expense of FSAA.
The bottom speed of the GeForce GTX 560 Ti is very poor although its average frame rate is comparable to that of the Radeon HD 6950 1GB. So, the latter card is preferable for playing this game unless you can afford a GeForce GTX 570. Take note that none of the tested cards can deliver a playable frame rate at 2560x1600.
