Um, I'm going to agree with Jeff here.. The GT is the best Bang for the Buck on the market regarding the newer high-end video cards.
I'm glad you like your 9800, they're excellent video cards, and great for the money. But they simply don't compete with a 6800 GT from a framerate standpoint, nor will they have the longevity of the 6800GT in the coming year.
Again, the 9800 is a great card. It's just no 6800GT.
I have a GT, and it works beautifully in all resolutions with AA and AF turned on and in most cases, cranked all the way or almost all the way up.
As they say, don't knock it till you try it
If there's anybody with the $300 for this thing, go for it. I paid $400 for mine when they were brand new and I've had nothing but great experiences with it.
