I don't have an "ultra portable" but I have a $2500 desktop replacement for work. It's got a 970m and a 6700K. Yes, that's a desktop chip, and it hits 4.2GHz

I don't have an "ultra portable" but I have a $2500 desktop replacement for work. It's got a 970m and a 6700K. Yes, that's a desktop chip, and it hits 4.2GHz nicely when needed. I mostly just tote it to the office and home, so it's quite nice.
