What sort of computers are you running Articulate Storyline 2 on?

Hey guys,

My organization is looking to upgrade our working machines, and I was wondering what kind of computers the community is using to run Storyline on?

I've read through the minimum requirements, but I'm more curious about what kind of systems you're using beyond that. For example, have you noticed articulate running smoother or publishing faster on machines with a certain type of processor? If so what kind of processor? How has adding additional memory improved your Articulate performance? Can you smoothly edit audio and video, and if so what sort of sound or video cards do you have installed? Have you switched machines and seen an improvement in productivity? Any idea what improved it?

I'm just trying to pool any information ya'll have on how to put together the optimal machine to develop courses on.

Thanks!
