Hey everyone! I'm coming from C4D where the CPU is more important than the GPU except you have Octane or Cycles4D ect. I really want to learn Houdini right now but my Macbook can't really handle this. I think im going to return it and buy a gamer laptop. Yes a laptop. I need/want it because i want to work everywhere i go. I know serious rendering is only possible on a desktop pc but for learning its ok i think. So what do i have to look out for? A good CPU or a good GPU? Thanks in advance!
