To compare the XFX 8800 GT 512MB XXX I reviewed previously scored 13546 3DMarks and the stock clocked PNY 8800 GT scored 12812 3DMarks. An 8800 Ultra XXX tested on the same system scored 14378 3DMarks.

FEAR
The first game test up for the XFX 8800 GT 256MB XXX is with FEAR. I ran the game at 1920 x 1200, all settings on max, soft shadows on, 4x AA, and 16x AF. The FEAR in game test loop recorded the following frame rate data:

• Avg- 52 fps
• Max- 109 fps

Quake Wars
The next gaming test was Quake Wars, which I ran at a screen resolution of 1920 x 1200 with 8x AA, all settings on high, and smooth foliage on. I used Fraps to record frame rate data from the single player Africa Refinery map. Fraps recorded the following frame rate data:

• Min- 32 fps
• Avg- 51.875 fps
• Max- 62 fps

Bioshock
The final game test up was Bioshock which I ran at 1920 x 1200 with shadow maps on, high detail post processing on, high detail shaders on, distortion on, real time reflections on, and all settings on high. I used Fraps to record frame rate data on the Fontaine Fisheries level where you have to leave weapons behind. Fraps recorded the following frame rate data:

• Min 32 fps
• Avg- 45/115 fps
