I have worked with numerous 2 screen setups, a single 29 inch U2913WM plus laptop screen setup and my current 40 inch 4k tv setup.
Honestly, I really like the 4k tv the most when I have a window manager that can make good use of that much area. Without the window management the extra space becomes a hindrance.
The larger screen that you are looking at is bigger than the 29 inch that I used to work with. That said, I did really like working with the larger single screen over 2. I felt more focused on what I was looking at and the it was still manageable with simple left and right pane controls.
All that said I wouldn't consider either of these as big of a jump as SSDs. I find the additional screen space is a nice to have feature but a SSD eliminates the pauses in my workflow. To me being able to hammer out a bit of code quickly without interruption is worth way more than the extra screen space.
