adamhm: Since it's just an issue with the integrated GPU, you could just get a cheap low-end card to use until you're ready to get a decent GPU.
Hi adamhm.
It's not just that, it seems that there are other problems with the new mobos (eg: audio, network).
Some people said that the drivers aren't ready and that it could even take 1 year for Linux to catch up properly.
Also that kernel 4.x is unstable at the moment and not supported by Mint. Maybe Ubuntu is a bit ahead, but I don't like its OS X UI style (plus the news about Canonical).
Wine? Even if cool, it still feels behind.. the games\programs list is maintained quite badly.
