As i said above will this spec:
CPU: Intel E3200 Dual Core 2.4GHZ (4.8GHZ Total)
GPU: On board Intel 3100 Graphics 384mb (Would soon be upgrading to Inno 3D 1024MB DDR2 GeForce 9800GT)
Mother Board: Asrock G31M-GS (I don't really know if it's good or not )
Memory: 2GB DDR2 800 Mhz
Is good enough for Wow? Maybe even TF2 with some upgrades?
