I think the biggest losers in this round are the people who bought 7000 series. If you had built a 6000 series from the start, you at got 2 years out of the system. But anyone who built a 7000 series saw their entire core system become obsolete in less than a year. At least anyone building a 8000 series today will benefit from a 2 core advantage.
I am one of those losers. I really regret going with this 7700k from my 2600k. Ah well, I'm stuck with it for a while.
