I have a Nehalem/Lynnfield i5 750 that still runs like a champ. Won't play modern games without a good GPU but otherwise does everything I ask it to, and is still pretty snappy for its age. The biggest reason it's not my main rig anymore is because of a lack of USB 3 ports.

I had an i5-750 with Maxwell GPU behind the TV for games with kids. It worked fine for a lot of things, but it ran out of CPU with Subnautica, which isn't exactly a AAA title, and I wasn't playing it when it first came out, but rather after updates presumably settled down, around 2018+. Overclocking may have given it a longer life, but I generally don't mess with that. If USB3 had been the problem, a USB3 card would be cheap. At about the same time I added a USB3 card to my main desktop for better SD card read/write speeds. I spend more on a good USB3 SD reader than I did on the USB3 card. Now the gaming PC is up to an i5-6500 with GTX1060. It is hanging in there fine for now. I'm only itching to upgrade it for Windows 11 support, but I don't really need Windows 11 on that machine.

I've got an i5 530 in a server in my lab. Since it runs idle for long periods it isn't very power hungry. It is also beefy enough for a lot of different loads.

I've found pretty much everything since the Core 2 Duo to be more than enough of for "server" tasks.

Likewise, my i7 920 continues kicking and handling most any random task I throw at it. I retired it as my daily driver in late 2018, but I sure got my mileage out of that thing.
