A year ago, strapped for cash but in need of a new computer, ended out getting a barebone powerspec with a Intel® D915PGN. I had to cheap out on just about everything hardware-wise, but was satisfied with the upgrade potential (for now at least). Money isn't going to be a tough issue for much longer though.
Not being one to hold back the spare change when it comes to system upgrades, I've been eyeballing a dual-core processor. The mobo's spec lists Intel P4 Extreme Edition processor in an LGA775 socket with a 800 MHz system bus. I'd hate to find out the hard way that a dual-core wouldn't work or require more than just a better cooling system.
Any help or advice would be appreciated.
