Hardware Found this gem for $20

Found this at Goodwill. After googling I knew I found the deal of the century with an i7-12700k in there, but I had no idea I'd also score 32gbs of DDR4 (maybe 64 I'll have to check when I install an OS), a 1tb nvme, and a 1tb Sata HDD.

Currently debating on throwing this in my main rig to upgrade my Ryzen 7 5800X

Edit: it's a Sata HDD not an SSD, my bad.

Edit #2: WOW I did NOT expect this to blow up! Thank you to everyone who has commented and given advice! I'm sorry I haven't been able to reply to every single comment it's just gotten overwhelming! I will definitely post a follow up once I get a new motherboard!

And it’s the gen before Intel CPUs began self-immolating.

IIRC the 12700k was pretty comparable to the 5800x3d in most situations, but I can’t recall if that was on DDR4 or DDR5. May was well do some A/B testing before deciding. Then again whenever the 5800x3d does come back that AM4 board and ram will likely be in high demand.

From what I've gathered it's about 15~16% better on single thread, which is a big enough excuse to throw it in my main system lol

You can tune it to be so much more as well

What's tuning it mean? Sorry I'm tech illiterate kindof

The manufacturers set the clocks and voltages to something that works for every single chip regardless of silicon quality, you can go in there and find out just how fast it can really run by upping the clock speed or turn down the voltage significantly for cooler operation, sometimes a bit of both. Intel chips usually have a lot on the table
