It works wonders.
Captain cannonfodder, it'll be fine. I run both the SMP and GPU client on my sig rig and it runs perfectly fine when I'm not gaming. (it's worth mentioning that I'm only running SMP on 3 of my cores, so I have around half a core unused at any given moment.) As long as you're not watching a movie or running something CPU intensive, you'll see almost no difference.
