>an i7 box and really anything from that generation
That doesn't mean anything at all. The i7 is a family of CPUs which can be anything from a 2009 i7-860 (with DDR3 support only) to a 2023 i7-14700k (with DDR5 support). Insane performance difference.
Sorry my comment is about finding hardware that affordably allows you to build a good gaming rig if that’s the sole purpose. There are plenty of previous gen cpus that will give most gamers 90% of what they want to play no need for the LATEST hardware. That dream is dying.
I think the point is that an i7, even from ~15 years ago, is probably sufficient for most gaming needs, especially if the game is primarily GPU-bound.
As long as you give the older CPU enough RAM, an SSD, and a good GPU, it probably is sufficient unless your doing sim-heavy games where you want the simulation speed to be maxed out (e.g. HoI4 later years max speed simulation)
