As I understand it, a "low end" i7 could result in performance inferior to a "high end" i5. And it's certain that understanding the hieroglyphic model coding of the damned things is a mega geek art form into itself......
That said, I have a lappy with an i5, 8gigs and a 256g ssd. I have mixed projects well beyond 30 tracks in Mixcraft. Your experience may differ, but it works pretty well for most general needs. Granted, you start running some cpu intensive/demanding stuff like multiple verbs/delays, Melodyne processing......
Results vary. Needs vary. The o/p's description may push the envelope, especially with a laptop. Or it may work fine.
There are other variables.
As far as my laptop goes, a larger ssd would be convenient. I find myself having to move stuff to an external drive a little more frequently than I would like.
I think 16 gigs of ram would also be a nice choice. And not that steep$.
The high end i7 however......
Pretty pricey, and I am not convinced it's mandatory given the o/p's description.
On the other hand, it's not a bad idea to select something with "headroom" for potential future needs either.
I am waffling. Not much help here!
My own experience = "buy all you can budget for, and plan on finding its never quite enough"
