Need $600 build with everything but os

Hello i'm having trouble figuring this out with so many options. I want to try to get everything including a decent lcd monitor, wireless keybord/mouse and a 2.1 speaker system.

I would prefer to have a am3 processor and ddr3 memory with a graphics card in the ballpark of a hd4850 if at all possible.

Machine will be used for general use, gaming and run windows 7. Once the machine is built it will not be upgraded so i don't need it to be future proof.

If you can help me figure this out i will order it tomorrow.

Good suggestions but I'd really try for a 22inch ws
