Upgrade Help

[Dane81]

Hi everyone,

As an avid wow player but complete computer noob I'd thought mmo-champion would be a good place to come to ask for a bit of upgrade advice so I can get my rig running as well as possible for WoD. I bought a dell studio xps a few years ago that is pretty standard apart from the GPU and power supply. I'm hoping to keep my budget under $500 and am after the most effective upgrades I can get for that sort of money. Being located in Australia I don't know if it is cost effective to go with retailers from the states and as far as I'm aware pccasegear is one of the better online retailers in Australia. A few specs are below. Any advice you could offer would be much appreciated. Thanks!
Processor: Intel Core i7 920
6GB Ram
GPU: GeForce GTX460SE
OS: 64 Bit Vista

to upgrade the cpu you need new mobo and ram. 500 aud is just enough for that. No room to upgrade that gpu.
