never had an issue with my gtx 550 ti always maxed ....
even my CPU is older, (core2Quad)..
Always consistant fps.
I do have SOME improvements (8GB Corsair 1600MHz, and a Boot SSD)
never a graphics lag, never a server access/internet lag....
Of course, I should mention I work for the local cable company and one of the employee perks is an unrestricted broadband pipe which is currently provisioned at 100 down 10 up. never a lag issue , even in WZ.
they see me rollin', they hatin'
