I have a 3847 Desktop & want to upgrade Video.

Again I have Dell Desktop 3847, Windows 10. I'm mainly doing Genealogy, on Ancestry.com. So I run at least a min. of 2 programs, up to 6 prgarms all at the same time. I just ran the Dell SupportAssit to test my current Video Card witch is the one on the motherboard. And all tested OK, but during that test the GPU was always at 99%!?!? Not sure if that is right. But have been thinking of using the windows 10 feature to have a split Screen or I have Two Monitors and could run them both if adding a updated Video Card.

But have though to do away with these two 19" monitors and getting a 22" or 23" and then split that screen would be better, and would not have a mouse issue betteen the two monitors, I guess. As I would really like to TALK with someone on the phone and ask questions. As I HATE ONLINE CHAT!!!! Its just to hard to write and keep up with the other person online. I hope that I have written this so you understand my needs for Video. Thanks!!
