Gigabyte X99-UD4 Motherboard Review

Rating: 8.0.

While the Haswell-E CPUs and X99-based motherboards of Intel's newest HEDT platform put a considerable dent in the pocket of any enthusiast, there are ways to lighten the cost burden. We recently reviewed the six-core 5820K and found it to be an excellent choice for users who value compute performance and want Haswell-E at the lowest possible cost. Another way to achieve an aggressive budget target is to buy a low cost X99 motherboard. 

That's where Gigabyte's X99-UD4 fits in. Do the features and performance make the sub-£170 board an interesting value option?


Despite its entry-level pricing for the X99 chipset, Gigabyte still manages to squeeze 4-way SLI/CrossFire support, an enhanced audio solution, server-grade power components, and dual M.2 sockets onto the X99-UD4.

Add those features to the eye-catching black colour scheme and a price point that makes it one of the cheapest X99 boards available, and Gigabyte could be onto a winner with the X99-UD4.
