Best budget GPU to pair up with a Ryzen 5 1600?

[GodIsMyName]

Well since I had some issues with the GPU on my new setup, you can check it if you want on this thread:

I need an upgrade!

So, I'm on a low budget (300-320€ maximum), I'm currently choosing between these two GPU's (but any suggestions are welcome):
980ti 6GB or the RX 580 8GB (both at the same price range, 980ti in used condition and the rx 580 factory new).

I've somewhat preference for buying it in second hand, just because i can test it before buying it to make sure everything works fine.

According to this website (which is not precise), the 980ti is the best GPU to pair up with the ryzen 5 1600, which i don't know if it's believable or not: http://thebottlenecker.com/

I currenly game at 1080p and i intend to upgrade in the near future to 1440p (not more than that).
I want to play current games with nice fps (i don't care about graphics at all, i just want the best frame rate possible.)

I also don't mind overkilling, i just want the best setup possible for the price.

If I'm not mistaken I believe the 980 Ti is more on the level of a GTX 1070. That would be the fastest card between the two. I wonder if the 980 Ti is still under warranty?

Yes, i found an ASUS Strix 980 Ti with warranty left.

That site (bottlenecker) is complete garbage, since you can test it out before buying I would easily go with the 980 ti as it's a much better card over the 580.

Yea, I don't know anything about that website, just found it randomly while googling, as of the GPU's, I've the same set of mind, I'm more towards the 980ti, since it out performs the rx 580 in most titles.
