You can't use DDR4 in your PC, look here. Neither your motherboard nor your CPU are compatible.

The Dell OptiPlex 790 Specs is 2nd gen LGA1155 Socket system, that uses DDR3 RAM... DDR4 is incompatible. But, 8 GB or more of DDR3 RAM should make it come alive.

Specifications say the Dell OptiPlex 790 includes the Intel Core i5 2400 CPU... are you sure your's has the Intel core i3 2100?... Use this app if you're not sure. https://www.hwinfo.com/

The Radeon HD 7570 is too weak for the Intel Core i3-2100... for this processor you need the Radeon HD 6970, RX 550, GeForce GTX 560 Ti.

Sadly, it is your GPU that is limiting your computer in games. Although 4gb will help a little, it won't help as much as a better GPU.
