[SOLVED] Should I upgrade my GPU or Display?

[Jeffsta]

I currently have a EVGA Geforce GTX 750ti Superclocked 2GB DDR5. I'm using a 40" HDTV 1080p which is either 60Hz or 120Hz, I'm not sure which. Videos work just fine on it, but I'm looking to start gaming on it. Games like GTA 5. Which should I upgrade first? I can't afford to do both, or even know if I need to update the Display.

Here's my Rig,
Case
GA-Z97MX-Gaming 5 Motherboard
Intel Core i5-4690k 3.5 GHz Processor
XFX TS550 PSU
HyperX Savage 16GB DDR3 1866 Memory

If we do suggest a GPU, how much can you spend on a GPU upgrade? Where are you located and what is your preferred site for purchase? Also, how old is that PSU?

I'm in the U.S. I would like to spend less than $300.00 on a GPU. I like newegg, microcenter, and amazon. I built this PC when I joined back in 2015, so the PSU is almost 5 years old. Thanks!

Okay, so I'm looking at the Tom's Hardware All GPU's Ranked. I can't help but notice that if I want 8GB memory in a GPU, which I was told was the "sweetspot", then I would either have to go way over budget to get a Nvidea GeForce GTX 1080 or get a XFX AMD Radeon RX 590 Fatboy, which would be under my budget and allow me to upgrade my PSU if needed. Is that Radeon RX 590 a good card?

You should look at a PSU replacement first before you drop any money on a new GPU.

GTX 1660 Super would be the suggestion then.
