Yea thats pretty awesome.

I'd really think that sata drives in raid would limit your overclock.
I have tried, and done 4 ghz no prob. on a ide WD 40gb hd. But i had trouble when using a raptor raid system to oc. I had the PCI/AGP fixed when ocing with the raptors.

Id like to see him get higher fsb. Itll be crazy.
