As I said in my initial reply, "Changing over the graphics card for a more powerful one does not always give the desired effect. This can be linked to..
The CPU "throttling" the card. I my case, I wanted to upgrade to a Nvidia GE Force 1080ti, THE card a couple of years ago. I found that my old i7 processor wasn't really powerful enough to do the card justice, so I upgraded to an i7 7700k. This gave the card the support it needed.
I'm not familiar with your i7, but the problem might well be throttling.

Re: Graphic Card Advice
So far the card has given me enough of a boost in frames that I think I'll hold off on any new upgrades for a bit. At least until FS2020 comes out and I get a better idea on what I'll need.
Re: Graphic Card Advice
Very good idea!
