Last year I got a macbook pro for design purposes I was using it for more light weight programs. But recently I got into using video editing software for example after effects, premiere pro etc. Soon I might get into 3D programs. I'm wondering since now I have 4GB of ram would I need to upgrade and would this help speed this up? Things are kinda sluggish sometimes at the moment. I have a 2.4ghz core i7. I don't remember the exact model of the graphics card but it's an ATI and looking at the GPU boosts I can get I realize unfortunately there will be no acceleration. This is unfortunate as there was no option from what I recall when I was purchasing to choose the nVidia GPU. Would the acceleration have made a huge difference? Would I be able to compensate with more ram?
