Fair points ... I am considering moving on from my i7 920 @ 4.2GHz rig (having trouble with mother board) and so am looking for 'evidence' of what comes next ... I aint convinced yet which way to go tbh! I game at 2560x1600 so being CPU bound is a rarity!
Right now Intel is the safe side.
If we start to see more of this (performance advantage at normal res) Intel is still not out as the i7 3770K is just as good in Crysis 3, i think it will take a bit from AMD for it not to be.
But 'if'...... the £100 price difference for the Intel will start to look ridiculous.
And Haswel is coming, but so is Steamroller, rumors are Steamroller will get a huge per core IPC boost, some are predicting +30% others even more but i doubt that very much.
However its likely to be significantly more % over Piledriver than Haswel over Ivy Bridge.
No doubt Intel will still have the efficiency advantage, but Steamroller should be a very strong performer.
Again Intel's prices will just look ridiculous.
We may soon live in interesting times again
