Upgrading a Dell Dimension 4600i

[beanymattd]

Hi there this is my first time posting on here so please bear with me.
Basically i'm looking to upgrade my Dell dimension 4600i.
The current specs are:

2GB RAM

Intel Pentium 4 CPU 3.06GHz (2 CPUs)

Nividia GeForce4 MX 440 with AGP8X Graphics card 64MB Approx Memory.

I believe it has a 250W Power supply.

I mainly use this for World of Warcraft, i'm looking to upgrade to improve my World of Warcraft game performance.

As far as i'm aware my graphics card is awful and needs an upgrade.
Please guide me with advice on what i should upgrade to.

Thanks

You should upgrade your PSU and get either a HD3650 or a HD3850.

Or would that be worse for performance?
