Another review of the 8800 GT can be found at BootDaily. They tested the card in CoH, Quake Wars, Lost Planet and WiC and conclude the card is definitely worth your money:
In all honesty, we'd really have a hard time recommending any other card than the 8800GT for purchase at this time – not even the GTX. Its price, performance and power use make the GTX look like a relic. Moving to the 65nm process has really paid some nice dividends for both NVIDIA and those whom are seeking the best graphic card out right now.More reviews should be online tomorrow when NVIDIA lifts the 8800 GT NDA.
