as a decade long "intel only" user i would have not thought i build myself an AMD system in 2017. and now i will maybe even build a second one around christmas.
i was going for x299 but hell has intels disappointed me.
cutting pci lanes, TIM, heat issues, 1000$ for decent number of PCI lanes... no thanks.
x299 is an enthusiast plattform so don´t cripple the usefulness by cutting pci lanes down.
threadripper looks like an awesome CPU.
i give the system a few month to mature and then i may replace my second system with a threadripper.
