Dear Mohsen,
it depends on the size of the system you are going to study, and on what  
you want to study.

I usually run small molecules (less than 20 electrons) on my laptop,  
systems with about 100 electrons on at least 32 processors (with dedicated  
high-speed network connection and filesystem), systems with about 1000  
electron require at the very least 128 processors.

best regards
