text: My boyfriend say the 6800 GT is a better video card.  It has 16 pixel processors and 6 vortex processors while the GS only has 12 pixel processors and 5 vortex processors. Both cards have 256 bit bus-width, 256 GDDR3 memory, and 1000 Mhz Ram speed. However, the GS has a GPU speed of 425 mHz while the GT has a GPU speed of 350 mHz.  Either card will produce great results.
