[citation][nom]mt2e[/nom]2700k here, have not seen any reason to upgrade to Ivy or even Haswell, a what 10% performance jump each generation and no other real noticable upsides.[/citation]
10% increase was bigger than I was expecting. IB was only a 7% increase over SB, so a 10% boost is at least noteable.
But then again, I am with you. I will be rocking my 2600 for a good long while yet. The issue is not one of if Intel could push more performance out of their newer chips... there is just very little that I do that sustains an appreciable load on my current processor. When I can play games at well under 50% load, why would I even think about upgrading? In a few years when next gen games start pushing hardware again then I will consider upgrading, but for now the only think I am hoping to upgrade in my system is a GPU with more onboard ram (but even my GPU performance is adequate, it is just some games like Skyrim that just eat all of the GDDR which then causes issues).
Intel can call me back when they have true 8 core CPUs for under $350, and things like DDR4 and SATA4 are available.
