How would my PC do on 2560x1080 (ultra widescreen 1080p) resolution

[FalerZasto]

So I have this pc :
-FX 6300
-8 GB RAM
-Gigabyte R9 380x
I am planing to get a new monitor since my current one is 720p so I was wondering should I go with 1080p or ultra 1080p . I mostly play league and csgo (I know it could handle them pretty well) but I was wondering about newer games like witcher 3,gta V, Black ops 3 etc.
Pls help me decide

those are not titles the 380x can handle in ultra, not to mention some of them are cpu intensive and yours is pretty low end.

Well for example you can expct GTA V to run on ultra at around 30-35 fps. Maybe less due to the cpu.
