It has 3 USB 3 ports. Your 1st Gen Focusrite Scarlett has USB 2 only.
So your interface will essentially be a good size paper weight.
you are paying through the nose for that graphics card (The Geforce gtx 950m). You don't need a gaming graphics card for Digital audio.
It also has only 2 logical cores per physical. which isn't the greatest ( I have 4/8).
Remember your going to pay more for a laptop than you would a desktop (value for the money) and if something breaks, your all done. where as a desktop you can easily open it up and interchange parts within seconds.
With all that said, if your only over dubbing a few vocal tracks, this will be fine.
Not my first choice, but it will do the job. Just take caution with Referbished computers.
I've never had any luck with them and my thought is, its refurbished for a reason, either someone didn't want it or it was a display model being drooled on in a Walmart
. Sorry I know I might seem harsh but im trying to be as honest as I can to help you out. I don't want to see you get ripped off.
