I would recommend that you take a look at a EVGA GeForce RTX 2080 XC GAMING, 8GB GDDR6, Dual HDB Fans & RGB LED Graphics Card if you are looking at upgrading.
A cheaper choice, and almost as good, would be a EVGA GeForce GTX 1080 FTW2 DT Gaming 8GB GDDR5X iCX - 9 Thermal Sensors & RGB G/P/M Graphic Card. This is what I am using currently.
The EVGA graphics cards have proven to be excellent and fairly reliable choices for me. I get my all my graphic cards over the years from Amazon.com.
