Tuba's system isnt bad. I would start with something like that. Get rid of Windows 10 Pro and just use the regular Home version. For gaming purposes it is perfectly fine and will save you about $90. Put that money you saved from Windows and put it into a good Samsung 960 Evo 256GB SSD, Then go get find the Biggest/Highest Resolution monitor you can find. And maybe get a decent Headset that you like the looks of. Those are the only real changes I would do.
