Hell, you can definitely run GTA San Andreas and Far Cry on that machine. So all is not lost
(except for productivity).

You will have to turn down some settings, but an HD3200 is able to play Far Cry 1 @ 1280x800 @ mixed settings with playable FPS. (It can also play FC2 at lowest settings at 800x600 and possibly 1024x768 or 1280x720.
GTA:SA will run at native res (if it is 720p or 800p) at mixed settings. (It really doesn't matter, the game doesn't really look good anyway)
PS: Crysis will run on that rig with LOWEST possible settings @800x600 but texture and water on medium and physics on medium.
PSS: To be honest with you, I don't know these things for sure, but I think that an HD3200 is better than my old ATI X1050 64bit 128mb- especially if it has some sideport memory. MY old X1050 could play all those games @ those settings @ almost 30fps- but dipping down to 22-25 briefly in heated sections. Crysis in singleplayer is still playable at 25fps in my opinion. It should only dip down to maybe 20fps very briefly.
