Uhm, long story short meaning my MSI products and those of my friends all were crap. We had to reinstall BIOS constantly (2-3 times a weeks). After changing our mainboards to ASUS, it ran just fine. I think since 2012 I've only reinstalled windows 2 times.
However, the mainboard I've suggested you can hold 2 GPU's AMD Crossfire I believe, not sure but it will do good with them don't worry. And ASRock is a good brand. They have a bad reputation, but they've fixed their quality issues don't worry. But if you want to have a real quality product you should go for an ASUS mainboard. Though it will cost 2x more (200€), uhm.
