All valid points, Anothertom!
Turns out Macs can use the external GPU in a Thunderbolt chassis as primary GPU for the OS by installing eGPU, which has been automated down into 3 easy steps. Instructions can be found here: https://www.techinferno.com/index.php?/ ... ay-output/
The consideration of price, technical limitations, and form factor are all crucial for any purchase. Think of it as a venn diagram, similar to the classic time / budget / quality conundrum. (You can produce work well, quickly, or for cheap, but rarely can you accomplish all three. You get two if you know what you're doing.)
Personally, I can see myself getting an Akitio Thunder2 with a 750Ti, all for around $350, and turning my Mac mini into a rendering/encoding/Resolume workshopping machine. (I did my research — it will all work with a 120V PSU). That would be my center section of the diagram (small, cheap, relatively powerful).
The laptop info you posted is really interesting, and definitely would make a beast for mobile VJing with Resolume. All things considered, the Wolfe and Razer Core are best suited to the use for which they are marketed — expanding a Macbook Pro to be capable of providing quality desktop VR.
