That computer could have trouble even playing facebook games let alone recent 3D games.... Not much can be done with it without spending way more than it would cost just to get a new computer. For surfing the web I would get more Ram if you can find it for cheap. I mean really cheap cause your computer is worth maybe $50 on a good day so don't go dumping a lot of money into it. I wouldn't bother getting a new graphics card either because your CPU will bottleneck even a $45 dollar Graphics card. So I would just save up a couple hundred dollars and buy a new computer, even the $300 models have 6-10x the performance and memory of what you have. For a real gaming machine you might be able to build a low end one for $600 here is the latest Tom's $600 game build http://www.tomshardware.com/reviews/pc-gaming-overclock... Good luck.
