OpenCV performance on a Laptop

Hi,

I’m looking to purchase a new machine for creative coding. Specifically, I will be using OpenCV, a kinect, audio analysis, fluids, and particles.

Ideally, the machine would be a laptop

I have an idea of what kind of graphics card I need to achieve decent fps with realtime audio visualisations and kinect image capture.

but I can’t find any info on the CPU/RAM requirements of openCV.

Is anyone out there using openCV realtime on a laptop? Which openCV functions? which laptop? which processor? how much RAM? what kind of RAM?

Can anyone on a MacBook Pro tell me which openCV functions are running smooth in realtime?

much thanks!
