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?
