Yeah these are right in saying you'll be able to turn it off/on in bios.
What i'm a bit confused by is the remark by Ownage that it could slow programs down.
I'd assume that it would only use the virtual processors if a program used it, and wouldn't be used at all if its not supported by a program. I'd also assume that running a program that supported it would use the virtual processors and so speed the processes up...
Surely this wouldn't cause issues? I'm not questioning you by the way, i'm just wondering (i have an AMD so isn't biased either to question you)
