Final Thoughts


I recently reviewed the Fatal1ty X99X Killer/3.1 and to be honest there are only two major hardware differences between the X99 Extreme6/3.1 and the Fatal1ty X99X Killer/3.1.


First the Fatal1ty X99X Killer/3.1 uses a Killer e2200, while the X99 Extreme6/3.1 uses an Atheros A8171, and second the Fatal1ty has a special USB port for gaming mice. Software wise, the Fatal1ty X99X Killer/3.1 is tailored towards ASRock's gaming line-up, you have F-Stream versus A-Tuning as well as a free trial of XSplit with the Fatal1ty board.


The Fatal1ty X99X Killer/3.1 costs $12 more than the X99 Extreme6/3.1 at Newegg at the time of writing, most likely because of its gaming theme and highly desired red color scheme. Overall, if you want to save a few dollars and want to same great USB 3.1 support, then the X99 Extreme6/3.1 is a good catch.




The X99 Extreme6/3.1 has the best USB 3.1 support I have seen on a motherboard to date. The board carries a wide selection of features other than USB 3.1 including dual NICs, Ultra M.2, eSATA, and some nice OC features. The downside of the Ultra M.2 is the inability to use the last 16x slot when using the Ultra M.2 slot, which also means if you use two GPUs, you won't be able to use the USB 3.1 add-in card either if an M.2 drive is installed.


The quality of the X99 Extreme6/3.1 is very high and that is apparent in the benchmarks and performance tests.
