Call of Duty 2
The PowerColor X1900 XT can’t win Call of Duty, although it nearly overtakes the GeForce 7800 GTX 512 and – when overclocked – the GeForce 7900 GTX. Here, the PowerColor is limited to 1024x768 resolution. The GeForce 7900 GTX is the only graphics card that gives you the comfortable minimum of 60fps in 1280x1024. The computational power of 48 pixel processors is uncalled for in this game: the Radeon X1800 XT is almost as fast as the PowerColor X1900 XT.
It’s rather useless to try to challenge the supremacy of the GeForce 7900 GTX in Doom 3. Like The Chronicles of Riddick, this game uses the OpenGL API and the special ability of the GeForce 6/7 architecture to process a double number of Z values per clock cycle (UltraShadow II technology). Anyway, the PowerColor X1900 XT looks good in 1280x1024 and even allows playing comfortably enough in 1600x1200 with enabled full-screen antialiasing and anisotropic filtering, especially at the overclocked frequencies.
