I am planning to run SB Pro PE on 3 different computers......not at the same time. So, at home i have and old AMDx64 2800 overcloked @ 3800, Nvidia GC with 2gig nvram and 4 gig of ram. XP pro, connected to my TV in the living room and used as a media center. My "good laptop" AZUS xv550 ,intel I7, E650 Nvidia + 8gig ram, W7 64 My "work laptop", Dell E6410, intel I5, shit GC no dedicated ram, 4gig ram and loads of "mandatory" software killing the performance of the machine.......... I guess (hope) i'll be able to play on any of them.
