FAST, lots of PCI lanes, and reasonably priced!

from completed build My little monster

This is a delidded part that I bought from SiliconLottery. They guarantee stability at 4.5GHz and 1.175V VCore, with AVX offsets of -3 and -5, and they don't lie. Using those settings and prime95, I got one core up to 85C, with a couple of others in the low 80s and some in the high 70s. Maximum power was about 225W. No problems whatsoever, rock solid.

At idle, all cores are sitting in the mid to high 20s.

Unfortunately I pulled the trigger on the CPU purchase way too early. I paid $680, and today you can get (slightly) higher spec'd processors for quite a bit less.

from completed build First Build After 10 Years

An fast CPU with it's 8 physical (or 16 virtual) cores and at 3.6 GHz. I overclocked it with 4.0 GHz without problems. I hope I can calculate my chess games even faster now ;P . Also price is more tha acceptable for that power. 1 point down: It has only 26 PCI lanes.

from completed build 7820X Monster

Intel 7820X: This processor is a monster and with water cooling I am getting great temperatures both under idle and under load. I will be using for multitasking, CAD, and etc. It has outperformed my expectations by many times over. Very happy with my choice.

Amazing. Used the ASRock easy overclock and set it to 4.7GHz. I have no problems.

Fantastic for simulation. Runs Hot. Not a good CPU for gaming.
