I am rebuilding a server from an old server. The main purpose is to speed up my sql server by using SCSI drives over IDE. I have a mobo I can use that will support my dual 1.8 gig xeon HT's that run a 533 bus speed. I can purchase faster processors with 800 mhz bus speed, but not sure if its worth it. What will be most likely to bottle neck my server speeds? Is the FSB a concern at all? dedicated sql 2000 machine with raids being built on 15K RPM drives (raid 0+1 on OS raid 5 on Data) 4 Gigs of ram.
