Hi all. My x299 MB is slowly leaving this world, and I need to replace it. I've read many reviews of x299 boards ( including Toms hardware), and I cant decide on one. My computer doubles for my gaming rig, and runs my wife's PhD research in genetics and bioinformatics. I was looking at MSI, Asus, and ASRock (Leaving out gigabyte because thats the MB I have thats diying). The boards I was looking at is: MSI gaming pro carbon ac, Asus strix gaming e, Asus prime Delux, and ASRock Fatal1ty professional gaming i9. I want to stay sub 400, but if the best option for us is a bit more I can swing it. If anyone has these boards and can tell me their experience with them, it would be appreciated.
