floeby,
Choosing the best graphics card is a complicated decision as the cards become more specialized. As I like to say it, content creation hardware is quite different from content consumption hardware. There are CAD / visualization programs such as Maya in which a $1,000 GTX Titan doesn't perform as well as a $180 AMD Firepro and GTX with astounding 3D performance. See:

> and a GTX really isn't usable in Solidworks. The workstation drivers just don't do well with viewports as this feature would slow gaming performance.
So, the choice is very much about cards that perform well in your applications, but as that might mean a wide range, it's necessary to have a good performance in almost every kind of program, which is to say- expensive.
The Quadro KX000 series were all replaced in September 2014 with cards (the KX
200 series) with more CUDA cores, more memory and higher clock speeds- much better performance and use less power. If I had an unlimited budget, the ideal card I would say is the recent Quadro K5200 (8GB), which has higher 3D benchmarks than a GTX 780, but it's also $1,900. The Quadro K4200 is also very impressive for $850.
More realistically, I would suggest you look into a card further down that same line, the Quadro K2200 (4GB) which are about Eur 500 and only use 68W. The performance surpasses the former series Quadro K4000. Still, a used K4000 (3GB) would be a very good choice and these can be seen for Eur 350-400 on Ebay DE. This is the card I recommend. See;

The Quadro 5000 (2.5GB) would be a good choice for the uses you mention- a 320-bit bandwidth and very good in 2D uses. However, it is now three generations past and I think the K4000 with more CUDA cores, more memory and 80W power use (+cooler) would be a better choice. The 5000 is a double height card and make sure you have the proper power connections- it's 152W and I think uses two 6-pin connections.
Another very good used card in that same price range as a Quadro K4000 is a Firepro W7000 and it has a wider bandwidth and more memory (4GB). See:
http://www.ebay.de/sch/i.html?_odkw=quadro+k4000&_sop=15&LH_Complete=1&_from=R40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR2.TRC1.A0.H0.Xfirepro+w7000&_nkw=firepro+w7000&_sacat=0
Still, as Adobe (and Autodesk) products are CUDA accelerated, I'd stay with Quadro. With a Quadro far enough up the line, everything is possible- though gaming will not be ideal except near the very top.
A word about Sketchup: I've found Sketchup to have a lot of limitations and having any kind of usable performance requires care and planning. In some ways I think the drawing setup is as important than the graphics card. I did a model of buildings totaling 1.2M square feet on a 200 acre Google Earth terrain and while this file was only 105MB, it gradually became impossible to navigate and eventually would not extract even 2D images. I took a few steps back and placed everything into components and Groups, and into Layers that could be turned off except the area I was working on, used monochrome view, and most importantly redesigned my trees fro low polygon count and subtracted 14M polygons. This made navigation possible but still, I can't get any renderings (VRay) of the whole model as Sketchup is a 32-bit program and my model pushes the memory over the 2GB limit. I think my future is going to be 3Ds Max. However, if your models are modest, Sketchup is very fast to learn and use.
