Ya, I believe its a mixture of 1703 + AGESA code. Then again, this is my 24/7 rig so I hate taking it down for testing all the time, but it wasn't THIS bad before everything regarding updates/microcode
Ya, that's pretty bad. Well at least you know what it is. My install is pretty much vanilla and made sure there wasn't many system interrupts which could've caused any whack issues, but ya.. That's quite a slow down.
