I arrived at a point when I have to choose betwin these two graphic cards for Inventor 2013 and 3ds Maxx Design:
GeForce GTX 650 Ti 2GB DDR5 128-bit
nVIDIA Quadro 600 1GB DDR3 128-bit
It think that everyone knows about the Quadro series from nVIDIA, but the GTX has 768 CUDA cores and the tehnology is the same as the Quadro, and the price tag.
So, what to choose? :)
At work I asked our techs the same thing regarding quadro vs geforce. Ultimately if you want to load large assemblies and not have to deal with lag or waiting time then go with the quadro. My workstation at work has a quadro 4000 and it loads anything in a minute or two. For a moderate user you'd probably only need about a gigabyte of video ram so a K600 would be fine and not to pricy. The Quadro cards aren't necessarily faster than Geforce models but with a quadro your ability to manipulate and load large cad files is going to be much more precise and fluid than if you were to use a geforce.
It's true, the GeForce will reduce the visual effect's during the construction of the part's but the final renderings will be clean.
I will make an upgrade to the comparation above:
Gainward GeForce GTX 650 Ti Boost Golden Sample 2GB DDR5 192-bit
nVIDIA quadro k600
I went thru the same type of comparison when I replaced my system about a year ago. The choice was between different nVIDIA cards, but it was still a GeForce vs. a Quadro.
I was fortunate to be able to work on a GeForce system before I ordered my card. It's true that both will final render about the same. On the GeForce card I found the image was noticeably slower to render, after a rotate or zoom. I opted for the Quadro because I didn't notice the same problem.
I've been very happy with the Quadro.
