I'm still running the very first i7 processor (came out in 2008), the i7-920 on this machine. With a simple 1GB video card, 12GB ram and SSD, i get a passmark of 1528. Win10 runs just fine.
I don't do serious gaming, so this machine seems to do all I need it to do...
I do have some machines with 3rd gen i5 processors and laptop(s) with 6th gen and 10th gen i5, and find that while they do run faster, my web surfing or spreadsheets are not really any different than my trusty i7-920 desktop.
Actually, I'm surprised that this old i7 still keeps up with most demands.
