You don't have OS to reuse? If yes, then it is up to you whether to get Windows 10, some people hate every Windows version after Windows 7, if you aren't a hater, get it then for the sake of DX12
Windows license key price is different everywhere, so you might have to find the cheapest alternative yourself, but I think Windows 10 Home version license key should be around RM 300 range if you get from official channel, or you can just buy Windows 7 key and upgrade to Windows 10 for free, this might be cheaper than getting a Windows 10 license key (able to reuse the Windows 7 key to activate Windows 10 starting from TH2 version 1511 update).
i've been googling around monitor which are good for gaming/photoshop but most of the models are not readily available over here
