I might update to a i7 in future, And one stick of RAM was faulty so I will have 16GB of RAM next week when they ship me my replacement.
I used to run the Intel Dual Processor as well, except mine was a Intel i5 Dual. But anyway, When I built my computer I upgraded to a nice Quad Core.
The one I'm looking at is a quad core,
this one specifically. I don't think they actually do i5 dual cores anymore, and i7 processors are pretty much exclusively enthusiast chips.
