Re: Which of these CPUs would be better?
Yep, they've pretty much nailed it above.
P2 for gaming, i7 for video editing, encoding, heavy calculations, etc.
I have the 955, but my board is currently dead, and I am in the RMA process.
Either one will be an excellent performer though. Just be sure to get an AM3 board, not an AM2+ board if you go with the 955. Both will work, but the AM3 only one will have DDR3 support, and will generally run better with the CPU.
