for 1440p get ryzen. ryzen 4th gen will come to shops in a month or two.
and for that cpu that cooling wont be enough at all. if runned without oc consider better cooler like Dark rock pro 4, or NHD 14 or nh D 15.
There are better ssd's than that in the same price range. like this one: https://pcpartpicker.com/product/HmmFf7/sabrent-rocket-q-1-tb-m2-2280-nvme-solid-state-drive-sb-rktq-1tb
get better airflow case. that case is decent but there are better options like Phanteks p400A/p500A/p300A. corsair 220t airflow, just to name some.
I would get slightly higer quality unit. rmx (not rm) is slightly better quality for slightly higher price.
wait for ryzen 5 4600 or 4700x to launc in a month or two. for 1440p gpu is more important than cpu.
