New Computer CPU Utilization

I just bought a new computer about a week ago and I was pumped about it. Windows was faster, games were faster, and applications in general were faster, or so I hope.

In the middle of a Supreme Commander game, I was just thought it would be interesting to see how my proc was being utilized, only to find out that one core is winding away with the other 3 sitting idle.

This phenomenon holds true for other games as well. So my question is this normal?

Phenom II X4 925
Geil 2GB DDR3
7900GT (I just ordered a 4890, so its on the way)
550W PSU (I just ordered a 650W for the 4890)
Win XP with all the updates

individual applications GENERALLY only utilize one core

parallel applications, like video encoding, are written to utilize all available cores

since you're only running the 1 game, you should only expect 1 core to be humming

do you mean you built a new computer? b/c if you bought one it would have come with Vista or Win 7.

anyway, since you seem to be happy with the performance, I wouldn't worry about it but I'll try and give you a hint in case some of the background tasks start to slow down your gaming. Right-click on the game process and set the affinity to to something other than 0 (in your case, 1, 2, or 3). That sets your game to run on a different core.
