It used to be that adding RAM was the easiest and cheapest way to speed up a slow computer. That never addressed the real bottleneck of a computer, which is the hard drive. I had a customer complaining that they probably needed a new computer even though theirs was only a little over a year old. Knowing that they had a standard platter-style hard drive, I suggested this. Boy is she glad that I did! Saved her hundreds of dollars on a new computer and likely thousands on lost time waiting for her computer to 'compute' as her entire business relies on her computer to make her money.
