TheTechLounge posted a review on the ASUS 8800GTX 768MB

The 8800GTX, after many months on the market, is still the best of the best. Sure, there's one card for competition: the 8800 Ultra; but that's sort of a joke; it's basically a stock-overclocked GTX, with a $150 premium. (The joke is really on the buyer.) ATI has given NVIDIA no reason to worry, since their HD 2000-series doesn't have a card like it. Without any competition to speak of, that leaves one question: which 8800GTX is best? That depends on the price, extra features and bundle.
