I'm very close to buying this setup. Prices are in CND Dollars. The company that builds them is called NCIX.

I'd appreciate any feedback from gaffers in the know. I'm not looking for a hardcore gaming rig, but something that will play most newer games at decent settings. I'm also planning on running this into my TV through HDMI, though if I'm not happy with how that looks (or feels, playing with k/m from a couch), I will use the LCD monitor it comes with.
No plan to O/C, at least not for a couple years.
