AppleWin's Config>Benchmark, reported a "Pure CPU MHz" which was not a good indicator of unthrottled speed for v1.26+, as it was still getting the emulator to do full NTSC/cycle-accurate video update. The reality (when in full-speed/unthrottled mode) is that the video is only refreshed at 16.6ms (wall-clock).

So added a 2nd "Pure CPU MHz" for full-speed (ie. no video update), eg:

---------------------------
Benchmarks
---------------------------
Pure Video FPS:	2860 hires, 2868 text
Pure CPU MHz:	10.3 (video update)
Pure CPU MHz:	241.3 (full-speed)

EXPECTED AVERAGE VIDEO GAME
PERFORMANCE: 476 FPS
