With this computer, I play on 1024 x 768, and my settings are medium/low. I sometimes (often) have some nasty lagspikes, but I guess thats cuz of my internet connection. The resolution is fine with me, but it would be great to run even gmod on highest settings without lag or crashes And well, if with that money possible, I recently started playing my far cry 2 again, but I have to play is on lowest settings and it still has pretty low fps, so it would be kickass to play it on the highest
