I know that it's possible to swap out some of the Xeon CPUs in Power Macs for other Xeon CPUs with the same socket. I have a 2.16GHz (Merom?) C2D white iMac. Is it at all possible to swap out my CPU for something a little faster. It's the one thing about iMacs -- everything else about my machine is terrific -- the screen/monitor, the harddrive, the motherboard, etc even the graphics I'm completely happy with. It's just the CPU is behind now.
