Eveytime I watch video tutorials on FCPX/Motion 5/After Effects, the software seems to run real smooth. On my iMAc, however, it really seems to slow down or lock up my overall functionality/multitasking abilities. So my question is, to get these programs to run smoothly, what are the minimum "best" specs I should have? Is it Quad Core vs Dual Core? Is it lots of RAM? Is it a combination of both? What will make the render time happen faster and smoother?
