Memory speed doesn’t really matter if your apps start thrashing

Edit: thrashing is very likely to occur on something marketed as “pro”. I have a work PC with 8gb of RAM, and my job requires me to edit video. I need to be careful on how big my video files are, because it WILL start thrashing. This is the reality. Professional apps require a lot of memory pages, and they are never open on their own.

Edit 2: I guess the thoughts from a computer scientist are less important than corporate marketing.
