Well, did testing today. Some things I have to mention.

I usually have Chrome open on one screen and Brave on another. Brave I use to watch TV and monitor a seldom used email account. Since that is all I do, I have no need for a bunch of plugins that were migrated from Chrome when I installed Brave. I deleted all of those plugins from Brave (but not from Chrome) and my CPU usage fell to next to nothing. I then loaded up my backgammon game and my solitaire game, both online browser based games, and they ran smoothly. So the issue was indeed CPU usage. I have been running those 2 browsers at the same time for so long now it never occurred to me that they were both running.

Between those replies giving me a roadmap of things to check, everything is good now.

Though I will probably still use this as an excuse to buy a new video card. I always liked AMDs. What this does is gives me some lead time to look at my mobo slots, find what I want that will fit, and wait for prices to come down.
