i need help in identifying the the best motherboard(s) that can be used to assemble a computer for video editing,graphics design and gaming plus the required accessories for optimum performance.thanks
Just the motherboard? Well, can't really help you unless you tell us your needs. Socket? form factor? expansion slots? usb 3? Overclocking or no? How many ram slots do you need? What "accessories" are you talking about? etc.
Assuming that all that is taken care of and we are comparing motherboards that are the same socket, they all perform the same. The practical difference in performance from one motherboard to another assuming the other components are all the same is less than 1-2%.
