amk-aka-Phantom,
You are just plain wrong and make stupid, blind assumptions.
I am currently at work, having a break and I am writing this from a HP Z420 with Xeon 2650v2 and a Quadro K4000 machine. We are using the complete Adobe CS6 and complete Autodesk Maya and Max suites 2015. This Quadro K4000 and its drivers are horrible. I have a scene in Maya set in meters and any time I zoom out 15 units away from the 3D model, the viewport displays corrupted geometry. Big patches of pitch black. The issue is so severe that it impacts my work. I am using the much recommended Viewport 2.0. Any options I tried do not fix the issue did not help. Switching from DX to OpenGL does not help at all. Texture corruption and more follows. I used any version of any type of drivers I found. (switched around 10 of em, clean installations of windows, etc). Wrote to both Autodesk and nVidia regarding this issue - nothing. All 4 Z420 machines with the Quadro K4000s have this problem both in Max and in Maya.
This problem is so dramatic, that I take my work from the office and when I get off - I go to my own GTX 650TI to load the scenes, because the dumb GTX 650TI just works. If you really think Quadro's are the bread and butter and savior - you are deeply wrong. Quadro drivers are worse then GTX drivers and the so-called support is laughable. I used many Quadro's, GTs/GTXs and Radeons over the years, and my-oh-my GTX cards have been mostly rock solid (with few exceptions), while the Quadro's got worse and worse. Sure, the Quadro K4000 can push 4-5 times the millions of polys my personal GTX 650TI can, but with all the corruption - that does not matter. Everyone in the office who is on the Z420s with the Quadro's is envying the guy next to us with a non-branded machine and a GTX 770. Things on the GTX just work.
Please, get some hands on experience with these, before you start commenting.
As it goes for the other point, GTX 970 and 980 are supposed to be high-end cards for enthusiasts. If they had 50W more of juice, those were going to be some impressive results. And for many generations, the top-of-the-line always pushes the envelope to the limit. Just because AMD does not have any competition, nVidia is not pushing the performance front as it was. Same story on the CPU side. When your competitor can't match your performance, you start pushing efficiency. nVidia and Intel are both going for small increments in performance because AMD is riding in the back seat, and while OpenCL and HSA are still a vision in the future, things are not going to change soon.
