What i call gaming, not a chance. Anything relativly modern. Crysis, Farcry2 COD etc may work at really low settings if at all but its no kind of experiance thats for sure.
What are we talking about here is it a laptop or a desktop computer ? If its a Desktop then its possable to get a better dedicated graphics card and upgrade the capabilities of the computer. If its a laptop then upgrading is a lot harder and in most cases just not possable.
