This is pretty wild. I fully understand why they are doing such a thing, but I find it fairly ironic. Their claimed cooling design must not be near what it should be if they have to lower the clock speeds to nearly half of the specs in similair PC parts. Dissapointing.
Even underclocked it's playing pc games in Windows great so this isn't a big deal for me. If this wasn't also my work machine I'd consider bumping it up a bit but don't really see the need to.
So far I've tested it with HL2 and FEAR and both games play great on high settings.
