Hi! Tomas
I've ThinkPad P50 with Nvidia Quadro M1000M 4GB GDDR5. I use it for rendering and playing games like NFS (Rivals, Payback), Counter Strike, DOTA 2, GTA V and FIFA 2015 - all in Med-High settings.. ( For tasks like movies, videos, etc. system uses internal GPU, i.e.: Intel HD530 ).
And now the main thing:
On software side, it is utilized by SolidWorks 2018 mainly, but I've used it for ANSYS, SIEMENS NX 12.0, MATLAB R2016a, AutoCAD, Inventor, 3Ds Max, Blender, Adobe (Photoshop CS6 Extended, Illustrator, Premiere Pro, Audition). Independently each software works quite well.
Since, I have 16GB GDDR4 RAM currently. My PC struggles sometimes when I use SolidWorks along with other heavy program like 3Ds Max. So amount of RAM also matters. But working on single S/W is always smooth and quite impressive graphic-wise.
This is the graphics I get to see while working normally on SW, without any lag:-

and If I apply materials and background also while working:

(Note that: I am far from rendering yet)
Finally, the performance you are going to get also depends on the workload that you are going to have on your system (and this is very important in deciding the specs). So, if you will be working on assemblies with large no. of parts then Quadro of Higher Specs would be better. But for simple assemblies entry-level versions are enough, given that they are latest. Try to stick with the latest release. Please!
I have seen my friends working on S/W with older GeForce & it lags- In rotating views, in rendering, in all things graphics. But, newer GeForce are quite impressive like 1080Ti and it even surpasses my Quadro in most comparisons, because its a newer release, with better performance.
Additionally, I'm not having enough money to add upgrades like SSD for now. So working with WD Scorpion Black HDD is enough for me now. But time-wise booting and loading times are higher. I'm planning to have SSD for myself. Thus, if you can have an SSD it is going to help.
So, If you are thinking of getting a system with Quadro I would suggest you to stick with the latest release in your budget. Also, the performance not only depends on GPU & CPU alone. You need to have an SSD also or at lower costs Intel Optane will work on Intel 7th gen and above processors. It prevents bottleneck, especially the Booting, S/W load times, game loading times, etc.
In AMD, Radeon Pro is also there. It'll be light on your pocket but with pros & cons. https://www.amd.com/en/graphics/workstations
I can help you in deciding specs if you're building a PC. I'm in such things since 2009.
I assume that's why you've asked for Quadro. Welcoming any further discussion.
Thankyou!
