all of the specs of that computer can run fpsc, and if you need, a texture editor, sound editor, 3d modeler, don't worry. For example, this specs are probably 6 times more powerfull than my specs:
core 2 dual 7500
4gb ram ddr2 800 mhz
9600 gt
win 7 ultimate 64 bit
and with my specs, i can rum deus ex hr with golden filter disabled and a big level of fpsc at the same time, i can get 40 fps at fpsc and 30 at dxhr, and the hardware you want is many times more powerfull than mine, so i'm completely sure that this computer can rum fpsc at an extraordinary performance.
