Sorry; 8600GS sucks. Your PS3 has a slightly better graphics chip (high end Geforce 7xxx equivalent), and the Xbox 360 is much better (High-end Radeon HD2000 equivalent).
As for the CPU, companies can optimise code more on consoles since there's only one platform to target and the OS isn't as resource-heavy as Windows is on a PC. The Xbox 360 has a triple-core CPU of a higher clockspeed and efficiency than a slow dual-core or worse you have, and the PS3 has an asymmetric one/eight core design with probably over ten times the peak calculation throughput of your PC.
So, despite costing less, the PS3 and Xbox 360 really are better than your PCs.
