New Computer Help

[TxSteve]

Hi all.

I'm a computer moron. I know practically nothing. I use my computer for: surfing the internet and for playing games -
Dungeons and Dragons Online
Lord of the Ring Online

Would like to play in the future:
Age of Conan
Hellgate: London

and would like to be able to play most/all games that come out in the next 2+ years

Below is what I bought for a comp; anyone point out any problems or obvious errors I've made?

Thanks in advance if you offer your advice (I have a monitor already):
