Build a computer

Hey! Once my motherboard burned out and with it everything else, only the power supply and hard drives remained, and of course the case. I mainly play CS:GO or other not very graphic games. The budget is certainly small, but I think for 20,000 r you can buy a Motherboard Video card RAM Processor and a cooler. Please tell me, or write a new composition of the computer for CS:GO.
Here is what I have already sketched:
----SAPPHIRE Radeon R7 260X video card
----GIGABYTE GA-970A-DS3P SocketAM3+ motherboard
----AMD FX 6300, SocketAM3+ processor
----DEEPCOOL ICEEDGE 400XT cooling device (cooler) ,
