My old P4 just quit running. I was shopping around and settled on a Dell refurbished Intel dual core with E6550 L2 4 meg 1333 FSB, 3 gigs ram, etc, for $459. I'm going to clean install XP sp2 over the Vista they have installed. It was too cheap to pass up. It should be 4 times faster then the old P4. I'm thinking of replacing my M-Audio Firewire 410 with the Audiophile 2496. From what I've read PCI is better than Firewire. Besides, I use an external mixer for the extra lines in. I hope I won't regret this purchase.
