Casual gaming rig help(wow user)

[GTX570SLI]

Hi im planning to upgrade my computer at work mainly just for playing world of warcraft and SC2. currently it's an P4 with 1GB of memory and running on an AGP 6200 128mb. i know it's ancient lol. I just need to upgrade my motherboard+cpu, RAM and Video Card. I dont really need a state of the art rig. Just something around 50-60fps with medium-high setting.

my budget are around 200-250 total

Im thinking of getting an i3 with an gtx210 220? 2gb ram?
how well is wow running on i3 and nvidia 210 or 220? any suggestion is welcome.

Athlon II X3 3.2Ghz
Gigabyte motherboard with good amd chipset
4gigs of ram
Radeon 4670 (destroys any geforce 210 or 220)

The total is 265$ and it will be far superior in casual gaming.
I think it holds a pretty good balance.

You can cut 10$ on the motherboard and get one of the cheeper ones.. they will do the job just fine.

You have to make sure that your Power Supply is at least a decent quality 400W
