So after the little Quadro 4000 incident I'm looking at walking the Cubix path Anyone here using a GPU-Xpander Desktop 4 with their OSX Resolve rig? I was thinking about starting out with one GTX680 and take it from there. How much does performance improve with each added 680 in a config like that? Linearly, twice the cards twice the performance?
How about going for 690s instead? More cores (and heat) but worth the cost and would it even work?
I don't really see how it could scale indefinite since the expander takes 1x16 lane and extends it out to 4 slots in a chassis. Doesn't that x16 lane hate to handle all four cards so that each card runs in what would be a x4 lane?
Can one mix cards in the Cubix and resolve recognize them and uses them? I mean if we start out with one 680 can we later add one 690 and one K5000 and they all work together like one extremely happy, and rather hot and steamy, family?
The host would be a Mid 2010 12 core MacPro with 24GB ram, 10.8.1 or 10.8.2 (out any day now...).
Enlighten me!
