You should think about gettin Clevo. P770DM/P771DM/P775DM/P870DM.
They are great workstations. And… with a desktop CPU.
Personaly I have P870DM with i7 6700k, 980M (single), 32gigs of ram (2x16) and 8bit IPS QFHD Screen (3840x2160). And I wouldn’t switch to anything else.
Clevo’s are like PC. They’re powerful DTR’s. And love to be upgraded with newer GPU/CPU (desktop socket). There are also custom vBIOS’es and BIOS’es to keep them modern and powerful.
Don’t be afraid of desktop CPU, in P870DM my 6700k doesn’t get hotter than 80*c under heavy load. And I’m not using overclock or 100% fan profiles. 
970M is minimum in my humble opinion. You don’t want anything slower.
P775DM and P870DM can be upgraded in future with QFHD IPS display (770 and 771 nope).
P775DM and P870DM supports desktop GTX 980 (180w for 775, 200w version for p870dm). And P870DM supports up to 2 gpu’s (2 mxm slots).
In future, you can also overclock your CPU and GPU. My 6700k has a profile of 4.4GHz (4 cores) with -40uV voltage. That’s free 400MHz on lower voltage than stock.
