The 8800 GS was a good deal when I got it recently for $110 after a mail-in rebate. With the stock cooler I overclocked an additional 24% by raising the GPU from 580 MHz to 720, shaders 1450 MHz to 1800, and the memory 1400 MHz to 2000 MHz, a 43% overclock. This videocard may be on par with a 9600 GT and close to 8800 GT graphics, non-overclocked of course.
At 1280 x 1024 , Crysis all max settings gives me very playable frame rates and an avg 35fps at 1024 x 768.
Also with COD4 at 1600 x 1200 all max settings I get an avg 40+fps
And with Supreme Commander at 1600 x 1200 all max settings - 35+fps
I think its now available on NewEgg.com for $120 after mail-in rebate.
