Computer help! Please...

I would build entire new PC if you have that money, since there is not really anything you could upgrade in yours today.

For 800$ you could get this one

This will play FFXIV at over 100 fps in any given moment on highest settings.

Or you could invest more into much better graphic card that will last you for much longer

For something around 880$
This will play this game even on higher resolution monitor screen with fps above 100.

@edit
Check it now i found i case with 2 fans on front of case so you may not need to buy fans.

Thanks! that will be a big help as well, i am kinda scared that the other parts HD and what not would slow it down or something

Absolutely not.
You could change the motherboard for more expensive if you want to (just remember to get 400+ series instead of 300, since they could not have updated bios and will not run ryzen 2 gen), however with stock cooler the power section on it will be perfectly fine due to the stock cooler air flow, and amd wraith coolers are really good made with copper pipes going around.

If you want to save a buck you may change the cpu from 2600x to 2600 without X so it will run cooler, since it is not going to overclock automaticly. None of the parts i have chosen in this build will slow down one or another. I have built about 10 desktops already for my friends, so you could relay on me.

Ultimately on your place i would wait for the GTX 1160 GPU to be released by Nvidia and ryzen 3 gen by AMD, so you could either have more efficient parts or cheaper.

Also one thing, never cheap out on the power supply unit, it is the crucial choice of yours, i recommend Seasonic (not evo series) or silentiumPC Vero series if it is available in the US. My two friends after a year of building the PC they both had a PSU failure, they have bought a cheap evga and corsair PSU and it end up for them with motherboard being broken and one of them have their GPU broken as well.
