Unfortunately, I don't think the 5500xt will handle it well. In some games it won't even run I think. You need a really good graphics card to get consistend 4k60 in a lot of titles. Also, if you don't buy yourself a really big monitor 4k is overkill in my opinion the sweepspot between 1080 and 4k therefore is 1440p.
For the Refreshrate all games with fast moving feel really nice (my games: Forza Horizon 4, Doom Eternal, COD, etc.) at higher frame rates.
