Need some advice for one of my machines for 3 boxing

[grettir]

I'm thinking about getting back to wow for abit with 5 boxing in mind, 3 comps, 2 older comps for one instance each and 1 main computer for 3 instances of wow.

The main computer needs to be able to run 3 instances of wow decently, doesnt need to be super fps but playable without going nuts.

Current spec of the computer is Amd x4200, 7300 geforce gt, 1 gb ram, 17 inch lcd.

The thought is to upgrade the display card to 8800 gt 512mb and ram to 4gb along with a 22 Inch monitor, that kind of stretches my budget but I'm hoping not to have to upgrade the cpu.

Any thoughts if this would work before I go ahead and buy the stuff?

Is the Amd x4200 a Dual Core? If so with your upgrade it should be fine.
