My CPU is E2200 @ 2.2GHz, did my PC able to run PCsx properly ??
In 2d game intensif such disgaea, la puccele games from nippon ichi or mana khemia from guts i think your cpu will be enought but in 3d game intensif like FFXII will be slow even with good grapich card. To play in decent speed in 3d game your cpu speed in 3ghz at least and dualcore.
Even with my MSI RX2600PRO GPU ??
Yes for game like FFXII but you can try game FFX, i saw this game is not as hard like FFXII.
