I asked support about hardware last week and got some explanation and links (thank you for that information), I read them all and still got a few more questions. Therefore I opened this new discussion.
First what I have read:
If I am right OpenGL used in FormZ for Full Shaded uses the graphic card. The better the card, the better you can model your daily work in 3D? or...???
Some suggestions say it's probably better to buy the iMac 5k then a MacPro 2013, because in 32Bit it will work faster and FormZ use only 32Bit during modeling. What exactly will be faster? If I model with my old MacBook Pro 2008 model most of the work I do in FormZ can be done easily, except rendering. Is it the finder that works more snappy?
I am planning to buy Maxwell Render plugin as well and this program ask for the best hardware, lots of RAM, lots of GPU and CPU. Then I believe the MacPro 2013 will be the better choice. Or..???
The main thing I don't get is the difference in speed during modeling between a 4.0Ghz CPU with 32Gb RAM in the iMac 5k and the 2.7Ghz in the MacPro 2013 12 core 32Gb RAM.
If possible I would like to understand these things before I can make the final decision to buy hardware before the end of this year.
Thank you all in advance.
