You've seen the results for yourself, so you pretty much know what I'm going to say. The 8800 GT does a very convincing imitation of the GeForce 8800 GTS 640MB when running the latest games, even at high resolutions and quality settings, with antialiasing and high-quality texture filtering. Its G92 GPU has all of the GeForce 8800 goodness we've come to appreciate in the past year or so, including DX10 support, coverage-sampled antialiasing, and top-notch overall image quality. The card is quiet and draws relatively little power compared to its competitors, and it will only occupy a single slot in your PC. That's a stunning total package, sort of what it would be like if Jessica Biel had a brain. With pricing between $199 and $249, I find it hard to recommend anything else.
