The ASRock X79 Fatal1ty Champion is the most complete LGA2011 motherboard money can buy. It has five PCI Express 3.0 x16 slots (although “only” four can be used at the same time) supporting both SLI and CrossFireX, 12 USB 3.0 ports, six SATA-600 ports, a professional-grade audio controller, two FireWire ports, two Gigabit Ethernet ports, a PLX PEX8605 chip to give bandwidth to the device that is requiring performance, and a special USB port called “Fatal1ty mouse port,” which has a polling rate that can be manually configured between 125 Hz and 1 kHz.
The main problem with this motherboard is, of course, its price. Costing USD 400, it is reserved for a select few who will need all the features it brings and who are fortunate enough to have the money to buy it. For the typical enthusiasts, there are products that offer better cost/benefit ratio.
