It does still matter for people using low-end computers. My MacBook's screen cracked while on vacation recently and I had to buy an emergency laptop. I picked up a device with a Celeron 6305 and 4GB of RAM. I loaded up Firefox like I normally do, and it was so slow and laggy to the point it was unusable. I then switched over to Edge and it performed significantly faster, and was using less of the 4GB of RAM. I was surprised at how significant the difference was, but there was no denying it. Edge performs much better than other browsers on low-end PC's.
