Laptop for Live Loopstation

I consider a laptop purposed for use as a loopstation a better value as opposed to a physical loop pedal. The obvious drawback is less solid functional control during a live performance, but I feel like there are ways around that fe: a seperate pedal control surface.

But I digress, what kind of specs do you all think I need?

Ram

Soundcard

Cpu

Gpu

Yada yada

Thank you.
