lolz... x-99... really? while x-99-ers have no real reason to go x-299 and their boards should still be good. for anyone without lga-2011-3... don't bother. ryzen 7 1700 and a motherboard can be had for less than the intel cpu with better performance and way lower thermals. only regret i had (only momentary) was not having the lovely quad channel memory. now i can wait for august and get a threadripper with 64 pcie lanes plus a motherboard for the same $1,000 that the x-299 cpu i'd be interested in would cost without a motherboard and with 20 fewer pcie lanes.
i mean quad sli at x16 for all four, where the intel would have to drop gpu's to x8. puh-leeze, no contest.
