I am trying to run some simulations on my robot model on a 7th Gen i5 laptop (ROS Kinetic + Gazebo 7) and the process tends to be very heavy. I can't even use my browser comfortably. I'd be looking for a system that can be used for the purpose, preferably with a good GPU.

Does Gazebo support new NVIDIA GPUs? What would be a good configuration in terms of processor, RAM and GPU (and how much do each of these actually count)? I am currently planning an i7 with 8/16 GB RAM and the NVIDIA GTX 960M.
