Graphic card
-
Hi, sorry for my english.
I Would like to know which card is the best for use with Sketchup. I don't use it for gpu render or games, i use it only for Sketchup.
I am considering for my choice quadro k600, quadro k2000 or geforce gtx780.
Is there a considerable difference during rotation of complex models?

CPU is your first and primary need for sketchup, then GPU. Personally I like the gaming cards because more and more renders are moving to take advantage of that architecture. I would say with the 780 you'll be screaming along in SU just fine. Although it might even be too big for just sketchup. The 770 would be a better investment on return IMHO.
-
with the same cpu (i7-4770k) do you think that the 770 and the k2000 or better k600 has the same performance? or 770 is better?

SU is notoriously hard to predict when it comes to graphics card performance. It's not rare for an objectively better card to underperform a much cheaper card. Also, as was hinted at before the CPU (or rather a single core of your CPU) is doing most of the work in terms of geometry. As I recall the GPU is handling things like shadows, textures, and (I believe) styles like extended lines.
My advice, if you're only buying a card with SU in mind, is to get a decent nVidia gaming card. I'm a bit out of date on my video card knowledge so I'm afraid I can't offer any specific advice with regards to the models you mentioned.

The argument between Quadro and GTX is long and varied. I'm not experienced enough to pick one over another. Personally I go for the cheaper and more versatile GTX.
there are lots of threads around where people voice their opinion on the matter.

I always have this question in my head: If I have a very good video card, will the GPU calculate the geometry instead the CPU?
I currently have a note with a i7 3632QM, and a intel HD4000, no dedicated video card. When dealing with very large models the GPU are using very little power while the CPU is full. I understand that the CPU is dealing with all the geometry and the GPU with texture etc. In this case i no longer need a better GPU. But if the GPU deals with geometry in very good cards its great news.
