Here's what I would do if I were you:
Gigabyte AM2 770 board, $75
2x1 GB DDR 2 800 RAM (any reliable brand), $30
AMD X2 550 CPU (3.1GHz, 6MB L3 cache), $102
ATI Radeon HD 4670, $70
That CPU overclocks well, has a better base frequency, and has much nicer cache than the e5200. You save about $20 with an AMD board, so it costs nearly the same as the e5200 and out performs it in every benchmark I've looked at. (It comes in around the Intel e7500.)
That graphics card is great for older games and good for newer ones at lower resolution with some reduced details. That is, it will WoW you.
