I am using iclone and Z brush kind of programmes and wonder if my cpu is enough to build the kind of environments you show . I would like to know if I would need an upgrade from 10 gb of ram for my 6 phenome cpu. Any info welcome .
Your cpu is likely good enough, but you would want a lot more than 10 GB of ram to work with UE4 and high end 3d content. I have 16 GB, and the editor easily maxes that out.
