I've attached some screenshots of my desktop specs as well as my WEI (Windows Experience Index) score. The WEI score indicates my weak link is the graphics card. Even though I have just 4GB of memory, that does not seem to get flagged. None the less, I built this desktop about ten years ago with some help and I have two 2GB sticks of memory in it. I don't game so its mostly used for email, surfing and YouTube videos. Will upgrading the memory make any noticeable difference as far as apps/browsers opening faster, etc. Is it worth upgrading and if so, to how much? 8GB or even more? If I go to 8GB, should I just buy two more 2GB sticks so all four slots will be filled with 2GB sticks or do it differently?
