~$700 gets you a pretty basic computer with 965m, you can build a desktop with gtx 1070 for 700$ to power a wacom display. And you will be able to upgrade it in the future, with Studio you are stuck with a 965m for $3000. And if you are getting a 980m for $4200 that leaves you with a $1900 to build a computer for Wacom, which can be way more powerful than 980m...
I think Microsoft should have sell that monitor by itself, but I guess this way they could not shovel win10 updates down your throat so it is not a good option for them...
