Okay, so I have the following: AMD Athlon2 x4 630 cpu, corsair 2GB DDR3 1333mhz ram, M4N68T-M mobo, WIN7 ultimate 32bit, WD 160GB ide HDD and crappy 450w psu that came with case. What would you guys recommend as a bare minimum upgrade if I wanted to start playin new games? I'm willin to set everything on low settings, anything to get decent fps.
