Upgraded from an AMD R9 270 to and RX480.
I have an FX-6300 and had to overclock to 4.3GHz in order to lower the bottleneck in my system

I previously got around 160fps average in csgo in a 5v5 game = R9270 FX-6300 @ 3.8GHz
Now I get between 60-80 fps in a 5v5 game = RX480 FX-6300 @4.3GHz

This doesn't make any sense to me. Please help
