    This CPU is a workhorse for multithreaded apps and multitasking. I built my workstation for photo editing, and the 7820x chews through anything I can throw at it, and it doesn't break a sweat. The high single core frequency is perfect for photoshop editing, while the 8-cores are ideal for Capture One Pro's multithreaded capability. This CPU, at $400-$450 hit the sweet spot for my needs.

    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.

    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.
