Most middle of the road games on average settings. MMO's etc will all be fine. Crysis will probably not run too smoothly on medium settings, but that is about it.
Aim to run your FPS at 30+ . Keep to 1280x1024 and keep AA off would be my advice.
For more info read the below and note that the benchmark system has a more processoring power;http://www.tomshardware.co.uk/geforce-gt-220,review-31703-8.html
Hope that helps.
