Im using the 6800xt which happened to be overkill for my 2k 144 hz wide monitor. Keep a note in your mind that the bench marks you see on YouTube are mostly on max graphics settings and you know that some games doesn't look good with all max graphics settings so you will lower some of the settings. For example, I lowered my settings on PUBG steam to very low on some parts and ultra on texture + high on distance. Im hitting the fps limit of 300 fps 90% of the time. If you can find a good price on a 6800 then go for it. (AMD is always working to improve performance just by updating the drivers)
