Okay, so, you purchased a Core i7 8086K for 450 bucks, and now you can swap it at AMD for that 16-core Threadripper 1950X. Well, it's not totally like that as its a sweepstake and just in the USA and limited to a set date, but you do have a chance to swap it out if you were an early 8086K adopter.

Our competitor recently kicked off a sweepstakes to celebrate the first 40 years of the x86 processor by giving away 8,086 limited edition processors.
