Redhulk50 It depends on your use case.
If its for gaming, its just a small upgrade with a faster processor and slightly better graphics. You wont see the full benefit of it because of the lens on the Q3s are not as good a the Q3, e.g what you will see in quality is pretty much what you have in the Q2. Yes the passthough is clearer and in color, but in game, hardly any difference
if its for VR porn/film, then no, Lens are pretty much the same and the resolution is virtually the same, you wont see any difference here.
I personally would wait and save a little more money to get the full Q3.
