Hi Atul,
If u can place those heavy tables in different data files then ofcourse it will improve the performance.
U can do this thru EM or by creating index in secondary filegroup.

Yes u can Check these
http://www.sql-server-performance.com/filegroups.asp says
If you know for sure that a very large table in your database will always be accessed sequentially, consider putting this table in its own filegroup, and then locating it on a disk array by itself. Be sure you don’t put more than one table in the filegroup and that no other files exist on that disk array. By doing this, you can take advantage of the disk array’s ability to operate sequentially to retrieve the data. Sequential access is always faster than random access.
