I'm not looking for performance gains, even though I only have a 750TI, and I'm mainly looking to do things like switch to DDR4 so I don't have to undervolt my DDR3 ram to 1.35V, change mobo, and change my power supply.

I am definitely doing the latter, but what do you guys think?

(Btw, I switched to an LG 21:9 1080p monitor instead of the one shown, still max all the games I play)

 

edit: I also have a G303 instead of a G300S now.

I'd do exactly what you said. After that, you really only need to upgrade your GPU.

Change the power supply first lol how has it not blown up already? After that, I'd invest in at least a GTX 950, as it has significantly more horsepower than the 750ti while being similarly priced. A good 960 is about $200 (I've been eyeing this one) https://pcpartpicker.com/part/evga-video-card-04gp41962kr. A good EVGA power supply like this one would be legit https://pcpartpicker.com/part/evga-power-supply-220gs0550v1. Mobo and RAM would not be my first concerns although it appears to be rather old. No matter what, get a new power supply of at least 80+ gold rating.
