I suspect this will still be the leading high-end gaming chip (short of using chillers and suchlike on the high core count variants). I would agree with Steve from GN that there's no sign of AMD thinking they can get near 5GHz all cores and yet Intel will chip a 5Ghz all-core gaming chip on the 9900KS, which will probably win on single-threaded performance too, in terms of IPC.
It's a strong launch from AMD and they are closer but it's not yet a return of the Thunderbird or Clawhammer days. Maybe they'll win on price but I'm still not convinced they'll top the fps tables, benchmarks, etc.
