I see the GT core speed as 400mhz and the GTX as 430mhz.
30MHZ and 4 pipes more for the GTX...
If you upgrade on a regular basis, go for the GT, I don't think you'll see much of a difference between the 2 with todays games, but if you plan on keeping it for more than a year or so, spend the extra 100 bucks.
