I'm at the recommended or above ,but this is one of those speculation threads to see how high on the settings you think I can take it.

Everything else is standard windows 7 adequate power supply etc, I'm not Super tech knowledgeable. I'm pretty sure the 4 things I listed are the most important though.

Definitely adequate. Probably decent framerates on high, maybe not ultra.
But i haven't played the alpha..
Ask somebody who has "seen some footage" *wink wink* played with a similar setup.
