Intel doesn't want you to use old equipment, neither does nvidia nor Amd, and their reach crosses many boundaries of many ppl, not just EA or Origin or Virgin etc. So when the public in general demands new games that have uber realism, massive amounts of data that simply cannot be coded into few threads with overly long strings, those 3 are more than happy to recommend a minimum level of new stuff, 6 core cpus, hyperthreading etc. There's even new games minimum of 16Gb ram and recommended 32Gb ram.
And it's only going to get worse. Dual core cpus are already obsolete, quads are on the verge, the plain 6core i5's will be next. Only the older i7's with decent IPC will last any length of time, my older 3770k is already starting to suffer from low IPC rates.
Turn on v-sync in game, or limit fps to 60 or below, running wide open is what's allowing the stutters, gpu is having to try and double up on frame outputs and failing when the cpu can't buffer fast enough.
