Hi BurrMan.

Thank you very much for your detailed reply!

You are very helpful :)

As I said I'm not in hurry and I will continue to search a very good possible configuration (compatible with my budget).

Your words are really helpful and clear :

@You : "Again my opinion was:
1. Power and stability = xeon/quadro mix
2. Lightning fast = i7 GTX mix
3. gtx and xeon, or quadro and i7 = bad mix..."

Thanks a lot.

The fact is that, as I said in my previous posts, I currently own a very stable and reliable Quadro K3100M,
that, although it is not comparable with modern cards in terms of computing power, it crunches all kind of software
that is in my current pipeline, both OpenGL and DirectX (2D and 3D)

My only fear is that a "GTX 1080 TI" will lack in reliability.

That is, if I can translate in "poor" words :

1) Sporadic rendering errors in rendering software (Thea Render, Octane, Istant Light...)
2) Incompatibility issues
3) Hardware components more "fragile" compared to a Quadro.

But i'm totally not and expert of these things...and I have also to consider that modern Quadro cards are TOO MUCH expensive..

Anyway...I take your suggestions very seriously!

Thanks again.
