I've been experiencing this same issue. I saw gnome-system-monitor go up to 200% at one point. I guess that's 100% for each core as it's a dual-core cpu.
I've attached a screenshot showing high CPU usage.
I'm using a relatively old Belinea laptop with an Intel Core2 Duo T7100 processor and 2GB of memory.
Ubuntu 12.10 (quantal) 32-bit
Kernel Linux 3.5.0-21-generic
Gnome 3.6.0
