@Johng - I'm super keen to know where you can buy an Xbox Series X console right now?! Let's now forget that later this year, AMD's Big Navi RDNA2-based PC GPUs will be out as well as Nvidia's next-gen Ampere cards. The bang-for-your buck equation will narrow considerably at that point, while keeping mind you will be able to do a wide-range of high-end computing tasks on you PC that you can't on a gaming console.
Let's also not forget that it is likely that both Sony and Microsoft will be taking a loss on the consoles when they launch that they will be looking to recoup through software and other licensing sales/fees. That said, the attraction of gaming consoles has always been bang-for-your-buck. Despite this, PC gaming is still going strong for a whole range of reasons and this is a sweet build for the right person - clearly, you're not one of them.
