Mostly play 3 games on my PC. NFS Shift (dual core) Il-2 (single core) and SF2 (dual or more core). First 2 are fine on my system (SB G860 with GTX 650 video card). SF2 is usually good, but sometimes bogs down when game throws lots of planes up, or in Vietnam campaign (the worst of the bunch IMO performance-wise). Will I notice much of a change if I replace the G860 (3.0ghz sandy dual core) with an i5-2380p (3.1 w/ 3.4 turbo) or am I wasting my money here? Thanks.
