ummm 8800 GT is ultra graphics and is only 240 or so depending on where u look. On par if not better than the 8800GTX and anything ATI has to offer.
We set out to find out if the GeForce 8800 GT offered a better gameplay experience compared to the GeForce 8800 GTS. After playing through the Crysis and UT3 demos the answer is quite clear, the GeForce 8800 GT most certainly is a better performer than the 640 MB GeForce 8800 GTS. In fact, it nearly matched the GeForce 8800 GTX performance at times.
Get it steve, save up that extra 30 bucks and you wont be sorry.
