I also have an AMD FX8 and would not an Intel if it was offered to me. Unless it was an I7 for a gaming rig that's different.

If you add 200 blank tracks in reaper the cpu should be around 2% if that.
And this I am running and Edirol FA101 10x10 at 1.2ms in /1.2ms out and I am on Windows 8 Pro.

One thing you must do before anything is disabling any CPU throtlling in the Bios

Just like the Intel CPU C1E issues this also applies to AMD's

GOTO YOUR BIOS

Disable these features!!!

-AMD Turbo Core Technology
-APM (Application Power Management) *disabling the AMD Turbo Core Technology via AMD OverDrive utility will also disable APM)
-C1E the major bottleneck is this one!!! power saving crap that funks up stability

Get that crap done first!!! I have seen this issue even on I5 and even I7 systems!!! for Daw work SHUT ANY POWER CPU SAVING SHIT OFF!!!

sorry for the harsh words.. but at least you have some directions now on solving your problem

C1E is one for the worst problems in recent computers for Audio interfaces
You get massive DPC spikes with it on.
DISABLE C1E IN BIOS weather you have and Intel or AMD.
