Thanks for the reply. Actually do not intend to use a discreet GPU. I am already using 3770, 4770, 4790k based systems for archicad, without separate GPUs. For my kind of work, the integrated graphics seem adequate.
The 5775c will obviously be slower for cinerender, which we use a lot. But I wanted to get a feedback from someone about the responsiveness of archicad in 2d navigation given the much faster igpu in 5775c. And whether any increase in that is worth sacrificing render times.
I know it is subjective. But would be nice to know from someone who is using a 5775c.
Ya, I am hackintoshing.
