Hey guys, I'm looking for a little help in upgrading my pc.

I want the most officiant, and cheapest way to achieve this.

• A video card that can play games to a usable point. And by usable I mean not pulling my hair out. 
• A good gaming keyboard and mouse.
• Anything else you guys think I may need to play games.

amd athlon 64 X2 Dual Core Processor 4000+

And thanks for the help.

I don't know much about how the amd's stack up, so I can't help you there.
Regardless, with a good video card, 2 GB of ram, and a dual core you should be able to play most games on decent settings. You can also plug in your 360 controller for most games as well if you don't like keyboard/mouse. I bought one just for that purpose! Good luck!

Your Processor is pretty good, one word of advice though. Get your Graphics card from Tigerdirect or newegg or NCIX. I impulsively got mine from the source and only realized when I got home that I had just payed 159.99 for a 59.99 card.
You should not need much for wow anyways.
