Because I don't have a hell of a lot of use for a server, this server is going to have the job of doing everything I'd ever use a server for: WWW, FTP, file storage, maybe VoIP, who knows. It's going to have a five-disk SATA RAID, hardware-accelerated so it doesn't suck CPU power. It's also going to use a Mini-ITX motherboard so I can fit the whole thing in a mini-SCSI case. The question is, do I get a board that can use a 2.13GHz P4M chip, or a board with 2x 1GHz VIA C3 chips? (I could also get a Core Duo board, but it lacks the PCI slot that I need for the RAID.) Obviously the P4M is going to be a higher-end design than the C3, but at the same time a combination file/web/FTP/etc server would benefit from having more than one execution core because there would be less interference between simultaneously-executing processes. So what do you think: would it be better to have one faster, newer core to run all these tasks, or two slower, older cores?
