Beefcake nice build mate, especially the processor!
Id have got the best one i could afford aswell even though someone said about a lesser model, if you got the cash get the best, thats my motto!
I had a 7600GT, was a good little card, just dont expect to much from it thats all ill say(maybe my standards are high i dont know) but anyway it will play all top games mid- low settings with good FPS.
If you ever think of getting the 7950GT in the future then thats an awesome card, ive got the one by Leadtek, runs all my games at highest settings/max screen res(battlefield 2142, FEAR etc) im well pleased with it.
8800........... if the 7950GT "owns" then i dont need to comment how good this card is!
