From what I've read, it's best to put tempDB on it's own physical disk (or array). For maximum speed, you could put in on a raid 0 array. However, if one of the disks fail, the DB server will become inoperative. If you want more redundancy, put it on a raid 10 array. The real key seems to be separating it from the other databases because there can be so much activity in TempDB.

How far you go really depends on the other databases on the server and whether they do a lot of work with Temporary tables, etc.

I haven't heard anything about multiple files based on the number of CPUs or cores.
