My Personal Rig has a 5900 NON-X model and a 3080ti If you want the performance of the 5900x, just overclock it you will save a lot of money. Mine is currently Stable at 4.7ghz all core overclock and has been for months. 1.39v cooled by an Issue h150i 360mm AIO. The only problem is finding one, I had to buy an Alienware prebuilt with it that I turned around and sold with a Ryzen 5 5600x. Ended up getting an OEM 3080 and the 5900 for a net price of $1000, (i traded that non-lhr 3080 plus $300 to a miner for the lhr EVGA 3080ti i have now) You have to be thrifty, but if you can get one, I recommend it! I just wish they would release these chips for sale to the public aside from prebuilt.
