The wiki definitely needs an update. I had the old client running and I finally noticed it hadn't downloaded a new work unit in a few days, and I go into find the new v7 client. Not sure how I feel about it so far. SMP started immediately, GPU was "waiting for idle" I need to see what it does to the heat in my machine, cooling has never worked well for me..
I tried to get the new version 7 client working, but I had issues with it. Currently using the FAH GPU Tracker V2 for my video card folding and the old version 6 client for my SMP folding. One weekend I might go back and see if I can get the v7 client working properly. The wiki does need an update.
