Howdy Pacific –
Laptops can work well – but make sure you get one that has the internal space for 2 hard drives because all kinds of problems can happen if you try to edit on one drive. Also – nowadays it seems that most laptop manufacturers are only using 5400 rpm drives – editing video works best with 7200 rpm or better hard drives. Solid state drives do make a significant difference but depending on budget you can get by on 7200 rpm regular drive. What will make render times go down significantly is having a 4 gig Nvidia card in the system. I would also spec i7 processors, a minimum of 8 ( and preferably 16 ) gigs of memory, USB 3 connectors, and an SD card slot, Questions – holler back.
