Having a MSI Gaming X RX480 8G
It's the 8GB GDDR5 model, and slightly overclocked to 1303hz
Performing fine, but if you want the "less tall" graphic card, go for the reference (137mm tall)
The one I have - and selling soon - is 142mm, which is super annoying space-wise..
Btw, is there a way to overclock the RX480 in macOS?
