I just got my proc upgrade. Went from 400mhz to 1.5Ghz. Everything is better.
Slight frustration: I pulled the heatsink off my old machine, and one of the screwheads was stripped. I can only imagine the over-zealous mac assembler putting chips on motherboards and just going a little crazy. Fortuantely I had a screw driver that I could use to get it off.
Slight excitement: Apparently OWC is out of 1.4 Ghz chips, so they sent me a 1.5ghz. Sweet.
