Alienware. Completely different story. The latest BIOS (I think it's A11) for the M17x R4 adds an overclocking tab for jumping up the CPU speed. That's nice, but there's still no option to turn off Hyperthreading. If I could turn off Hyperthreading then I'd be more interesed in overclocking as I'd expect to see about 10*C temp drops which mean 10*C overclocking leeway.
