MDE, I wasn't looking at prices, I was looking at the level the cards are promoted as. The 6800GT is billed as a competitor to the X800 Pro. The 6800 Ultra is billed as the X800XT killer. No sure what the 6800 Ultra Extreme Edition kills, except everything else on the field.
Spike, too true... Who gives a flying F which memory is a few MHz faster than the other. At the speeds we're seeing, you WON'T know the difference. I do know that going from the 9800 Pro I had before, to the 6800 GT was a MAJOR upgrade. I can only imagine what my next card upgrade will be like (12-18 months from now).
