21.5 imac configuration.

So I'm planning to get a 21.5 imac. I was thinking I would get the fusion drive and i7 processor. I was going to play some games on it. Do a little Final Cut Pro for YouTube. Record the gamely on my ps4 and edit those videos and maybe do a little website building.

would this be best for my needs based on the information I posted above or should I try something else?
