Vas ist los!
Check out Game PC article on Dothan, Pentium M 780. To confirm your suspicions on the M being the best single threaded CPU for GS3.
I will be be seeing my obnoxious DAW builder this weekend. Will pass along his fan/swap trick, and OC'ing tips to you next week. His Gigapulse instances are so high, and his case temps so low, I'm considering jumpimg on this setup. If it works with my current GS3/Scope rig, it will be a no brainer for me. My 3.4GHz ES has been stellar so far, but if I would have waited another month. Oh well.
As I said, if high Gigapulse instances is a priority, this has even beaten the AMD 55FX!! Haven't heard anything on the 57 yet, but I'm sure it'll be more of the same.
