Intel's Haswell-E or X99 platform is of course their high-end desktop platform and is made for extreme setups. Well the X99 motherboard we are taking a look at today definitely fits that description. Today we are checking out our first X99 workstation motherboard and it comes from ASRock. It is the ASRock X99 WS and it has all of the features you would want in a high-end motherboard like 4-way SLI and CrossFireX support, a powerful 12 phase power design, server-grade LAN chip support, support for ECC memory, 10 SATA ports, an Ultra M.2 slot and of course ASRock's Super Alloy design. You can build a pretty insane system with this motherboard, let's take a look and see how it holds up to our tests.
