Sorry, my questions is:
On my 2010 MBP 13", I notice that when I do 3D effects (extrude and bevel) I normally get the wait bar when it has to render and such. For instance, I draw a circle or square or whatever then fill it in, then do the 3D effect bevel and extrude. Whenever, I select preview it needs time to load and this process becomes more complicated when I add other effects then return to the bevel and extrude effect. This may have more to do with the program's limitations -- I notice on my activity monitor that processor is only working 50% (at most) while the rendering bar is up. The faster i5 wouldn't speed this up, would it?
