Command & Conquer 3: Tiberium Wars
This game having a frame rate limiter, you should compare the minimum frame rates in the first place because it is the minimum speed that determines your playing comfort in Command & Conquer 3.
You can’t play the game normally on the ATI Radeon HD 2600 Pro as it gives you a frame rate of 14-15fps with slowdowns to 9fps. Note, however, that the Nvidia GeForce 8600 GT isn’t brilliant here, either. The GeForce 8600 GTS and Radeon X1950 Pro are the only cards to ensure comfortable gaming conditions at 1280x1024 and with enabled FSAA.
Like in most other games, the PowerColor HD 2600 Pro 512MB is slower than the ATI Radeon HD 2600 Pro due to its lower memory frequency. Both these cards are far from the acceptable minimum of speed.
