The large Turbo button ! It offers an on-the-fly overclock, bumping the FSB up from a standard 200mhz to a whopping 240mhz ! This translates to 2.4 Ghz system speed! Excellent boost of speed, a 20% overclock!  We ran the games again and compare the results!

Overall gaming framerates improved by a few FPS. Newer generation games are more dependent on the GPU, and even a 20% increase in clock speeds for the CPU did little to achieve fantastic framerates. The Geforce 8600M GT GPU on the GX600 is pretty decent for a DX10 card, and we'll have to wait and see if DX10 gets tuned up to better performance through patch releases and driver tuning.
