Now that Vegas supports dual processors, which motherboard / CPU combinations would you recommend (Having overpaid my taxes by over $10k (thinking I owed)), I have a post-tax gift that is my due).

I currently use an AMD 64 3000 on a Gigabyte board (1.5 gig ram, 5 200+ gig harddrives (plus 250 gig backup in a removable tray). I would like to stay with a dual AMD 64 processor system so I can take advantage of the next 64 bit applications.

Any suggestions?
