hey, My radeon x1950 pro is 575 core clock while my geforce 7900 gt is 470 core clock. WHen i put in geforce 7900 gt in computer, i noticed games like stalker/battlefield 2 run alot of smoother compared to radeon x1950 pro, but how could this be? Im not really knowledge about grapihc card but judging from the core clock, shouldnt radeon 1950x pro run better since it has 575 mhz core clock?
