Laptop CPU for virtualization.

[hwmgr]

I am confused b/w Intel Core i7 3612QM & Intel Core i5 3210M.
I'll mostly use the laptop for network testing and penetration, so i would run Windows 2008 server, linux, on Virtual Machines (VMware or virtualbox), and may run 2 or more VM's at same time.
What processor should i select & will it make a huge impact from i5 to i7?
I'll be having 8GB ram.

If you feel that way there isn't any question about which option to choose, right?
