Very very very important - NOT filegroups, files. For any database, not just tempdb, you may gain performance by having the same number of files per filegroup as you have cpu sockets or cores ( don't do this for hyperthreading ).

Putting tempdb on it's own array is another matter and not directly related to database files.

here's an example to create an 8 file tempdb

use master

go

Alter database tempdb modify file (name = tempdev, filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db1.mdf',size = 60Mb,filegrowth = 20Mb)


use master

go

Alter database tempdb add file (name = tempdev2, filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db2.mdf',size = 60Mb,filegrowth = 20Mb),

( name = tempdev3, Filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db3.mdf',size = 60Mb,filegrowth = 20Mb),

( name = tempdev4, Filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db4.mdf',size = 60Mb,filegrowth = 20Mb),

( name = tempdev5, Filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db5.mdf',size = 60Mb,filegrowth = 20Mb),

( name = tempdev6, Filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db6.mdf',size = 60Mb,filegrowth = 20Mb),

( name = tempdev7, Filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db7.mdf',size = 60Mb,filegrowth = 20Mb),

( name = tempdev8, Filename = 'D:\Program Files\Microsoft SQL Server\MSSQL\data\tempdb_db8.mdf',size = 60Mb,filegrowth = 20Mb)

go

Oh and you dont need to assign a db file to a cpu. The whole point is that if you have 2 x Quad core CPU's then thats 8 threads. Wach thread can access 1 file, so in theory 8 threads = 8 files in a group = the setup shown above.
