Get the 6800GT and sell the X800. With the $100 left over and the roughly $150 from the X800 that's $250. I have a Logitech 5.1 system that's like 270watts max and it was only $220 and it sounds awesome. Bestbuy has this system. I know Klipsch(however it's spelled) are nicer but I really can't tell much of a difference between this system and theirs. The sub with the Logitechs is huge also.
