Im currently running a computer with
Core i7 950
6 GB of 9-9-9-24 Corsair Ram.

I am looking to upping my current amount of ram to 12GB.

Is it better to buy two packs of
Corsair XMS3 CMX6GX3M3C1600C7 6GB DDR3 3X2GB DDR3-1600 CL 7-8-7-20 1T Core i7 Memory Kit - Corsair - CMX6GX3M3C1600C7

or to buy one pack of 6GB of triple channel ram?

I'm using all the ram for numerous VM's and I keep running out with just 6GB.
