Intel, what are you doing? The X299 platform is so confusing. This is the first time we’ve had the opportunity to look at two X299 boards side by side, to identify whether one is better than the other. To do that, we had to choose a selection of parts. For X99 and Z270, the choices were obvious. Here, though, we have processors ranging from $250 to $1,800—and higher—so what do we use? Is this a high-end platform or a mid-range one? Ultimately, we had two choices: either the high-clocked 4.3GHz Core i7-7740X, or the 10-core Core i9-7900X. We went with the middle ground, at least until Intel starts shipping six and eight-core samples out to us reviewers.
