Took my $99 Phenom II x2 560 BE and MSI 785G motherboard combo, hit the unlock core option in the bios, and have a Phenom x4 "B60" is what Windows reads it as, but thats because a 960 doesn't exist. 3.3ghz stock, and its running pretty easily @ 4ghz with a $20 Cooler Master heatsink at stock voltage. Not too shabby!
Very excited to see how this puppy is now that its got essentially 4x the processing power, and a real hard drive in it (I just swapped from a 5400rpm notebook drive I had laying around to get it up and running to a Samsung F3 1TB). The drives are cloning now.
