You seem to have left out a lot of relevant information:
"Still, it’s not a complete victory for the Xbox One X. PC gaming doesn’t require an optical drive, after all, so you can enjoy 4K gaming, 4K video content, and HDR through digital downloads. (The RX 580 will handle all that just fine.) That already drops the cost of the cheaper build we priced out.
Beyond that, these builds could change the closer we get to the Xbox One X’s launch date. When AMD’s Ryzen 3 line launches, it might offer even better CPU performance for the same price as the FX-8300. Prices might come down for RAM and Pioneer’s 4K UHD Blu-Ray drive. Availability for the RX 580 may increase again. And of course, the holiday shopping season should yield some sweet deals on at least some of these build components. By November 7th, the Xbox One X may be far easier to reproduce as a punchy $500 PC."
