Silicon Lottery was great. Perhaps oddly I never used them for any of my desktops rather a few laptops. I'd get the top binned CPU I could buy from them and tweak the clocks so that single core was OC'd to the max and multi core was relatively close to stock but undervolted. This kept fans from going nuts without having to sacrifice a great deal of performance.

I really wanted to get my 5950X through them but the shortages at the time made it hard enough to get one at all and they eventually gave up even trying to list them.
