Performance Mainstream Graphics Cards
The GeForce 6800 GS and GT are definite winners in the Battlefield 2 performance-mainstream championship with nice results even in 1600x1200 resolution among. While the RADEON X800 XL, X800 GTO and the X1600 XT 256MB are generally pretty fast too, their performance is enough for those who do not use resolutions higher than 1280x1024. The GeForce 6800 is a clear outsider with framerate below 60 even in 1024x768.
The situation looks a bit different with the eye candy mode on: the RADEON X800 XL is faster compared to the rivals, but not considerably. All graphics cards mentioned here, except the GeForce 6800, are capable of playing Battlefield 2 with all the bells and whistles activated in 1024x768, but all of them are not able to score high FPS in 1600x1200.
If you are choosing a performance mainstream board for playing Battlefield 2, pay attention on the GeForce 6800 GS or the RADEON X800 XL: the former performs better without antialiasing and anisotropic filtering, whereas the latter offers great speed in eye candy mode.
