Hi, I want to buy a new rMBP 13 but I come from a PC so I have some doubts regarding the hardware. I want to run a virtual machine, mainly Linux for work, but sometimes Windows. My doubt is whether the rMBP 13 supports virtualization VT-x and VT-d. In terms of configuration I also have two doubts: - RAM: 8 vs 16: in normal conditions 8 GB is enough for me, but when running one VM I was thinking that 16GB can be useful. - CPU: i5 2,6 GHz vs i7 2,8 GHZ: do you think that the i7 processor has a great advantage over the i5 when running a VM? What do you think?
