I'd actually like to see varying overclocks... maybe an Athlon XP1700 at it's stock speed, then at 2.0 Ghz, which is an attainable goal on stock voltage... then at 2.2 Ghz, which is the average I think... and then at 2.4 which you might get to if you get a good stepping... and then of course, if they haven't already maxed it out, find it's max, whether it's 2.5 or 2.6... whatever's stable.
Then maybe do a Price/Performance comparison... swap only the motherboards and CPU's in the rigs, and see which combo gives the best performance for the money... that will put an end to half the AMD vs. Intel arguments.
