They are on the new process and they are nice overclocking CPU's... one gent had his up to 3.3GHz on his highest attempt, rock stable. Unfortunately the lack of L2 cache (only 128k) affects it dearly, and it is by no means a performance king.
I picked one up about three weeks ago and it's great fun! Got 2660 with default vcore, and 3GHz with 1.55v using stock HSF. For some reason I can't get it stable with all 3D apps when at 3.2GHz, so I'm just going to keep it at 3GHz. At this speed it provides about the same gaming performance as an XP1800+ (maybe just a bit better), but it's hard to argue with the "cool factor" that comes with a 3GHz CPU!
