DOOM 3
Running DOOM 3 in the good-looking high-quality mode, the XFX card returns a ~50FPS average at 1280x1024. That's enough to make a fast-paced FPS playable enough for the most part. Even 1600x1200 is reasonably smooth, with a little slowdown in frenetic sections. What's also telling is that this GeForce 6600 DDR2 card is twice as fast as the ATI RADEON X1300 Pro at 1600x1200.
Adding 2x FSAA and thinking again of the target resolution of 1280x1024, things begin to get a bit sticky. If FSAA is your cup of tea, we'd recommend the 1024x768 setting. Still, XFX's card is around 40% faster than the vanilla GeForce 6600 (DDR1) 256MB SKU.
