Pretty happy with mine so far. Haven't really pushed it yet (need to sort out cooling), but seems to be running fine at 3.6 (401 x 9) cpu 1.38v (in bios) 1.65 mch. Nice little setting that mch. At 1.58 it crashed right away, at 1.65 happy as larry.
Haven't orthos'd it yet, but have been doing lots of 3d rendering , with radiosity, 2 threads, and it's working a treat:)
