I use a simpler, far more common (for lkml participants) workload:

Dell notebook, single P-M-2GHz, ATI X300, open source X.org:
(1) build a kernel in one window with "make -j$((NUMBER_OF_CPUS + 1))".
(2) try to read email and/or surf in Firefox/Thunderbird.

Stock scheduler wins easily, no contest.
