If you're going to be multitasking with your laptop or desktop, it is best to boost RAM as high as you can afford. If you can, upgrade the random-access memory on your existing machine or choose the highest sensible option when buying a new computer. With more memory, you can have more tabs open while browsing, you can edit larger files, etc. 4GB is the minimum for Windows 10, but it will probably result in frustration eventually. Linux actually runs better with a small amount of RAM, alternatively. Also, don't forget to replace a spinning drive with an SSD.
