Nice review Stulid.
Have to agree with Humbug and Martini, overall Kaveri is a little lackluster, but when it eventually replaces the 6800K price point, it still serves a purpose and is ok for what it is. At the current price point it's just to close to Intel i5 territory, or Haswell dual core + dedicated GPU territory. It's def price that is theh killjoy here, the actual CPU is ok.
To expand on this the current price point of the 7850K (£140 on OCUK) is only £10 less than a Athlon X4 760K* / HD7770 combination. This can use the same (cheap) A88x motherboard and will offer much better gaming performance and roughly similar Similar CPU performance with a mild OC (4.2Ghz across all four cores).
*Basically a 6800K minus the iGPU.
As another example I only paid £30 more than the 7850K RRP for my wifes 760K / HD7850 setup. As this was primarily built as a gaming system the extra outlay is easily justified.
Like you I think this needs to fall to around £100 (current 6800K pricepoint) to be relevant in the current market.
