RadeonPro CPU usage

Anybody use this program for overclocking while monitoring their CPU usage by having Afterburner and Rivatuner open? When I'm just using Afterburner, my CPU usage doesn't exceed 30% (or if it does, rarely) on all 4 cores, with most of the load being placed on core 0, but when I'm using RadeonPro Core 0 jumps up to 95-100% with maybe 25-35% on 2 other cores for all games, no post-processing and everything is handled in-game. I'm taking it this has something to do with the CPU affinity settings being integrated into the program? Just having core 0's affinity set on while turning off the others crashes the game. Because yeah, when I play a CPU intensive game at some point I'm pretty sure there's going to be a bottleneck because of this if I were to continue using RadeonPro.

I have a 3770k overclocked at 4.9 ghz, and combined with the above info it's apparently not the processor itself nor should it be from having two overclocking programs open (as far as I can tell).

I like RadeonPro because I can force my GPU to max out at the overclock without the fluctuating clock speeds that downclock sometimes as much as 200 mhz in Afterburner when the GPU isn't being throttled, which as far as I can tell doesn't have much of any impact on games, but is something that I'd just absolutely prefer not to happen as newer games become more intensive (the game being used to "bench" the card is The Witcher 2 maxed out with uber sampling on at 1080p, which is still pretty intensive considering at these settings I have to set my fps to 30 or disable uber sampling for 60).

I'm starting to get really annoyed with this reference 290x card, I got a good deal on it and it's pretty top-notch as of now, but this Powertune integration or whatever it is that causes clock fluctuations without the ability to disable it in a program other than RadeonPro (?) is super annoying, not to mention AMD's crap overclocking software which made using a third party program necessary in the first place. This all makes me want to go with Nvidia next time, if not just for the sake of consistent clock speeds and because of AMD's arbitrary implementation of Powertune, I don't think hardly anybody wants an equivalent of Turbo Boost in a GPU and at least Turbo Boost can be disabled.

Any advice or thoughts on the CPU usage?
