cheap i7 prebuilt.. need advice

[Bordoh]

I've been looking at a new computer and trying to either piece together or buy a cheap prebuild i7.

I'm considering this one... its a refurbished Asus:

Would this be a wise decision, or are refurbished computers generally a bad idea? I've never bought a refurb before, but $700 for this setup did seem rather reasonable.

I'm upgrading my old comp which is just useless (p4 1.7 ghz, radeon 9700.. complete crap). I know this will blow it out of the water, but how would it do at running newer games? I plan to get diablo3 when it comes out, but don't know if this would be enough.

any input is greatly appreciated.

Thanks
