What to upgrade on a budget.

[True_Scotsman]

So I have a smallish budget of around 500 to upgrade my pc, but dont know what to keep or what to upgrade.

Current spec is :-

ASUS P5QL Pro
4GB DDR2 OCZ Gold
Intel Core2Duo E8400
512MB HD4870
Corsair VX550w PSU

Various Hard Drives but these will be kept no matter what I upgrade.

So whats the best bang for buck upgrade?

Case is the Dragonlord K62, all of the hard drives are SATA apart from one 1TB one (has a lot of pics/vids of my daughter on it)

PC is used mainly for some games WoW/Diablo3/GTAIV and some others nothing too high end.
