I'd agree with you if the laptops were having the same issue. But hey, I got another piece of the puzzle for you.
So, if I go turn my router off, reset it, whatever, when my connection "comes back", I have NO internet at all and the freezing/stuttering crap returns.
If I completely shut my pc down and turn it back on...same issue. No internet at all, freezing/stuttering.
HOWEVER, if I RESTART the pc, my internet returns (.10-.30 max) with no freezing/stuttering.
Yeah. How fucked up is my pc?
