In theory yes, though you'll still need a lot of disk bandwidth.
I'm using a Razer Blade Stealth (Kaby Lake version) with an nVidia Geforce 1080Ti in a Razer Core and it's doing pretty well, as long as the disks can keep up.
I'm getting pretty good results with this combination, though with effects and color grades it does struggle a bit with 8K footage. Black Magic raw is less GPU/CPU intensive than Redcode, but more disk intensive. Such is the trade off.
