I recently bought COD world at War and noticed my 7900 GS is no longer getting the job done like it did for cod4 for some reason. Basically the same game engine. Regardless being the college student I need a quick budget upgrade. I'm tossing between the EVGA 9600 GT and EVGA 9800 GTX. The 9600 GT has core clock of 740 mem 1950 and stream processors 64 The 9800GTX core is 740 mem 2200 and stream p at 128? the differnece in cards is $62 but is it really worth it? Any help would be appreciated.
