will Kaveri effect CPU prices of AMD

Richland APUs will likely go down around $5 I would guess. As for the FX series CPUs. No price change since Kaveri APUs have less processing power.

Only the release of Intel's Broadwell CPUs may have an affect. If Intel goes back to double digits (%) performance gains with Skylake in 2015, then that should have an affect on AMD's FX prices.
