Performance in Simulators
A small difference between the bottom and average frame rates is a characteristic feature of this game which makes overclocking such cards as Radeon HD 6870 unrewarding, even though they can be with some luck overclocked to the level of the Radeon HD 6950 or even made faster than the GeForce GTX 560 Ti at 1920x1080 and higher resolutions.
Performance in Strategies
As we proved in a previous review and as is indicated by the results of the gaming tests above, an overclocked Radeon HD 6870 can challenge the newer Radeon HD 6950 in some situations. It finds it harder to compete with Nvidia’s solutions, though, especially in games like BattleForge. The GeForce series always has a higher bottom speed here as opposed to AMD's products which cannot keep the frame rate above 15-18 fps.
StarCraft II: Wings of Liberty
The Radeon HD 6870s run this game quite fast, especially when overclocked, at resolutions up to 1920x1080 but cannot achieve a playable frame rate in the Ultra HD mode. The GeForce GTX 560 Ti can’t do that either, though.
