The Rampage III Extreme has had a bit of a makeover - the Black Edition is, well, a lot darker than before as all the ports and sockets now don a black and dark grey coat, rather than a dash of red as well.
Firstly you'll notice the heatsinks have also been upgraded to match the Maximus IV Extreme. If you look carefully at the VRM heatsink there's even an ROG logo stealthily incorporated too.
