I think it is going to spoil the shit out of me.
Imagine being able to change your BIOS settings w/out leaving a benchmark. I was clocking with cpu-z open and nothing else. I would get 8 - 10 mhz bclk at a time without incident. That is huge once you figure your freq's in during say 3dmark 06 between cpu and gpu tests. That could mean monster scores on normal runs. I'm sure it takes a little finesse and a lot of timing...
