# of files in group, CPU, and RAID

Not sure if this is the right forum...
I have a fact table that ha sits own filegroup on a dedicated RAID 10 array.
Somewhere in Books Online I read that you should create a file in the
filegroup for each CPU in the server. My understanding is that in SQL 2000,
this triggered the server to spawn multiple threads to handle the I/O. My
questions are:
1 - Does SQL 2005 need multiple files to spawn multiple threads for I/O?
2 - If not, being on a RAID 10 array, does it help in any way to have
multiple files in a group?
Thanks,
