So, I had a Radeon RX 570 4 GB which I used for 5 days and Did not like its performance, So I returned it and bought a Radeon RX 570 8 GB (For free because they are the same price in my country) Then after the Radeon RX 570 8 GB Arrived and I tested it, I did not notice a performance improvement, Perhaps barely 1 more FPS, But why??
