I think you should have taken a pass on the 5800 because it was
basically a mistake to ever
release it.
Even Nvidia jokes about the 5800 and admits its not a good card.
Return it and get the 5900
before its too late.

400 bucks on a 5900 ultra that isnt out or 200 bucks for a 5800 Ultra? - All
my games ru VERY well and this card has give me a bigger performance boost
than I could have hoped for....
