Thanks chew
Problem is, I usually don't have enough time to switch OSes during benching. I rarely have a whole day for benching, more like 2-3 hours a time, and in that time I usually fight with clocks not with software. I'm trying to do serious benches when I have time to prepare everything. All results I am really proud of have been made after long hours of sitting in front of a monitor, listening to rotary compressor... nothing good ever came from short sessions of benching in a hurry. (yes, call me captain Obvious )

As for AMD benching, there are a 965 C3 and a 790FXT-UD5P here that are begging to be frozen but it'll be at least a week until I can arrange "something volatile" as you call it.

EDIT: I'm on Classified 760, with 1,575 volts real
