FWIW,

I was able to import for texturing in the PAINT room a 5.1 million poly OBJ on my little weak Macbook with only 8 Gb memory and crappy 1.2 GHz Intel Core M

The Paint room is where you can AutoUV your models and apply smart materials, which would be pretty great. Good luck!

So.. I would think it would work for a more powerful machine. :-)
