My TR3960X came in today, the TR3990X is on order :-). Since my current chassis isn't configured for liquid cooling I went with an air cooling solution and it is freakishly large, seriously.
From where?!? All I can find is B&H Photo with a pre-order estimating a month wait.
Just hoping I don't have to wait as long as I did for my last CPU - an i7-6700k. It was quite a few weeks after "release" before I could actually buy one.
I'll probably stick with 32GB of RAM for now - I don't run a lot of VM's or anything - but I'm going to try an Intel Optane as a main SSD drive this time. Thinking about the Aorus Master sTRX40 since I'm a bit partial to Gigabyte for motherboards. These TRX40 boards are not cheap.
