I've been reading reviews about the difference between the i5 and i7 processors, but nobody really talks about whether the i7 provides any substantial benefit for running VMs. I have both Fusion and Parallels - latest versions, and while I only run one of them at a time, I often run at least 2 VMs side by side for development purposes. I'd rather by the less expensive i5 and start saving for a decent SSD (though for now I'll start with just a 500 HDD 7200rmp) IF there's no real benefit in my going for the i7. But if there is truly a benefit from the higher processor when dealing with VMs, I want that. Anyone have any experience or info about this? Thanks!
