Is buying an Apple iMac w/ M395X+32GB RAM+1TB FLASH STORAGE+4.0GHz I7 an overkill? I plan to edit videos with some photoshop. I want to keep this computer for a long time too. I'm sick go buying a new pc every 2 years. Will the performance and speed keep up over the long run? Please provide feedback if you have this setup. or should I be waiting for the upgraded iMacs and buy it in a similar spec?
