I have a I5 3570K running at 4.5 GHz, I had decided to hold out on upgrading until broadwell and the gtx 800 series comes, this I5 and my gtx 680 are holding out pretty well since 2012.
But looking into preordering FRACT today (after brad mentioned it on the UPF) I noticed that they put as recommended settings a "Core i7 2.4 GHz or better", of course they probably recommend that because of all the synthesizer craziness they have going, makes sense that this would be a game that would take advantage of better multithreading.
But that got me thinking, would upgrading to a I7 3770K be worthwhile? for holding out till the next gen intel processor at least, or would it be just a waste of money? do you think games nowadays take more advantage of HT?
