Core i7 CPU Usage

[Gizmotoy]

For those of you with a new i7 iMac, if your machine is completely idle, what does your CPU usage look like in Activity Monitor? I'm routinely seeing Finder consume 70-90% of my CPU. The single CPU bar meter view in the dock is basically pegged most of the time. The graph shows it as system usage.

If I open the CPU History window, all 8 threads look like they're just about maxed out. Any ideas what is going on here?

Definitely something going on there. For me, Finder sits at 0.0% CPU at idle.

Taking that into account, I went ahead and tried rebooting. Now CPU Usage is back to 0%. I'm not sure what the issue was. This iMac just came this week, so I don't even have much of anything installed yet.

Keep an eye on your CPU usage, guys. Hopefully this was just a fluke and isn't a bug in a driver somewhere.
