uhhh...
I would disagree. I only have 1 gig of RAM in here...and this CPU is junk, therefore I say its the SAME 7600.....you must have.... da da da, bad drivers. Like 80% of the xt5000t users out there, sadly. Search around for some GOOD ones, everex are junk
edit:
that picture is my screeny lol. >9000 in aquamark 03
Thats an impressive score dude, I am already jealous.
XT5000T would die if I played Crysis demo at Medium settings even at 800 X 600.
On a side note, what driver version are you using?
