Well I tried 7 on my main rig and didn't really like it :/ Lack of features and options on install and it did not want to utilize my card at all, detected it but would not actually use it. Maybe I just been using the console version for so long 7 seems really weird to me. Think I'll give it a bit more time before I try again.
Under the hood is my main computer which is a phenom quad (only 1.8ghz) with that fermi card. Than there is the Dell Power Edge 1u server (2x dual core opterons at 2ghz i believe). That server only runs during the day as the girlfriend doesn't like the noise at night. Than there is a lappy not even sure what it has besides being a dual core.
I have been planning a build for feb-march and had originally planned to go sandybridge and water for OCing but changed my mind and going to go with a FAH twist that will ensure I can fold the big adv WUs post february when the requirements change to a much more commercial style. Once I have it solid I'll post but from other people I have talked to running this setup I expect aibout 280k-300k ppd. That will give us a heck of a boost and it turns out actually being a bit cheaper than the 2k I originally planned on spending
