I'll add my own experience here, Gigabyte DS3 , solid 24/7 E6300 1.86 GHz, zero blue screens, zero lockups at default clock over 9 months, ditto at 2.8 GHz, but a few problems at higher than 440 fsb and really tight memory timings. It's about 3 times as fast in F@H as the Thoroughbred B @ 2 GHz I'm typing on now.

Also used a 2 GHz Clawhammer A64, solid and stable on S754, but wouldn't overclock past 2.3 GHz, major errors showed up past 2.3 GHz. Performance on F@h was dog slow compared to the overclocked E6300.


Here's hoping that Barcy does well, or Intel will increase clock speeds at a snails pace, Penryn will be expensive, and Nehalem won't show up till late 2009.
