Why do you think so? I'm workin in a lot of programms like zbrush, rhino, Houdini, realflow. About C4d - again, WHY do you think so? This program is rly good for modelin n have a lot of instruments for make a rly good stuff. And about my pc, i worked on them 5 years n i know what it's capable of, topology/materials is ok, just enviroment/light setup/shadows/blur/good materials.
