I tried using this for gaming then realized the 260x isnt powerful enough ,besides that everything works fine
The 260x should be powerful enough to play any game at 1080p no problem. Not at max settings but it will not just flat out not run games.
The new triple A games run at 1080p but around 20-30 fps
You should get more than that at low settings.
I have a XFX R7 260X and I don't get much better. Lately I've been playing a ton of XCOM 2 and I barely run at about 30FPS on medium. It's getting annoying for me. But I do have a FX 4350 overclocked to 4.7GHz so it might run a little better with a FX 6300. Most older AMD cards 280X and older are starting to have lower FPS with games I've noticed. But AMD did announce that the Polaris will be releasing later this year so maybe it will be time to upgrade then.
