upgrading pc components

for very little, you could get a RYZEN 1600/2600, a motherboard and 16gb RAM for under $350 right now. you already have a GPU so that's something you could upgrade later. there's a ton of nice cases out there as well if you wanted to refresh your entire system for another 50 to 75 bucks. dollar for dollar RYZEN offers the best bang for the buck.
 

i buy it 20 nov but my budget is around 1200 for mb ram,processor and gpu since i have the other components myself
