Arma 3 PC build to run on ultra 60 fps?

What would be a good PC build to run Arma 3 on ultra at around 60 fps. I joined a realism unit and currently run arma off an older lenovo laptop (got it last year) and it just isn't doing as well as i want. I got a good paying job so money isn't really an issue. What would you recommend for a GOOD PC build? I'm great with assembling them and software etc… But am not really the best at deciding what parts to buy. Also needs to be wireless or connected via ethernet cable MUST HAVE BOTH OPTIONS and i do like to watch movies as well, i do not need a monitor because ill be using a TV i need a powerful desktop PC and also maybe a good gaming mouse (the one i own now is a cheap walmart mouse) it would be nice if it could also run GTA V on ultra or high. Plus do you recommend i7 or AMD and what are the benefits of both?
