Call of Duty 2
The Gigabyte GeForce 7900 GTX enjoys a certain advantage over its opponent in Call of Duty, too. But again, this doesn’t matter much. Both the cards are sufficiently fast in 1280x1024, but cannot maintain a playable average frame rate in 1600x1200. The gap between the two cards from Gigabyte is expectably getting smaller in higher resolutions. They differ by only 2fps in the hardest display mode.
Doom 3 prefers Nvidia’s GPUs, too, and the reasons are the same as with The Chronicles of Riddick: this is an OpenGL application and it uses rendering methods optimized for the GeForce 7 architecture. Yet even despite this handicap, the Gigabyte Radeon X1900 XTX is less than 10% behind the Gigabyte GeForce 7900 GTX in the standard resolutions with enabled full-screen antialiasing. The average performance of both the tested products isn’t lower than 57-62fps.
