Hi, Jake, 

   I don't mind at all.
   I think I have 4 GiB of RAM in my Lenovo laptops, dual core, but I don't have a 64 bit processor (only 32). I suspect, though (only suspect!) that things will run very well in your setup, as long as you don't have to do REALLY memory-intensive calculations.

                       Best wishes!
                           Curtis
