Yeah there's a difference between LE and then the Limited Edition presented by eVGA....but the people have been assuming it's the LE which generally is the more mainstream model opposed to performance.
But like everyone else I still say 6800GT is your best bang for the buck since you can OC it pretty well..
Did some people here forget about me and my plain 6800 with the 16 pipe softmod
Actually hadn't realized you had done that
Did you flash the VGA Cards BIOS to be able to get the 16 pipes?
