If I wanted more than 8 cores, the 12-core ryzen 5900X is $549, can you really get an intel 10-core cpu for the same price, or within 50 bucks plus or minus, that performs better?

I'm seeing the i9-10900K for $467, but in terms of dollars/performance per core I think it's still behind the ryzen which costs $82 more.

I wouldn't look at the 10900k trying to "save a buck" on the high end. Instead the 10850k which is, for most purposes, just a 100 MHz slower 10900k can be found on sale for 350$. Higher availability, and prices that meet or are below recommended MSRP.

You can't really get a 5900X for $550, they're sold out everywhere. (I'm trying to buy one myself.)

The 8-core 5800X is available at MSRP, though (at least, I've seen Newegg stock it).

The biggest issue you're going to run into, is that the 5900x may be $549 retail or whatever, but where are you going to buy one? I recently opted for a pre-built 4600G PC, and the 4700G is a great price point too... unfortunately AMD decided to really open these up to OEMs.

Can you get the 5900X at all?

Not to mention, where would you get an adequate GPU to go along with it unless you already have one.

GPU is not a prerequisite unless you're into gaming or ML. For someone like me, a GeForce 8800GT is sufficient, but I'll take all the cores and RAM I can get.

Some form of GPU with modern display out is needed for some multi-monitor setups (mostly 4k), even if you don't do ML or gaming. Unfortunately there are also many motherboards out there that only support running one 4k monitor at 60 Hz even if the integrated graphics support more.

if you are going to use the GPU solely for the video (output) acceleration then you still have many options that can do that but (fortunately?) can't mine digital currency efficiently.

Don't know about that. Here in France, I've just checked Amazon for a cheap, relatively modern GPU and the offer has dried up (at least those sold by Amazon). I'm looking to run a GPU-passthrough virtual Windows on my linux PC without integrated graphics.

I bought a RX550 a year or so ago so my father could run a 4K screen. It cost around 100 euros at the time. This would be ideal for my use case, but now I can't find one. Are those even useful for mining?

On the nvidia side, all you can find is some GT 710. Not sure those can run 4K screens (didn't check). Even the GT 1030 is hard to find - a few months ago they were everywhere.

I wouldn't recommend buying a 5900X for gaming; you're going to be bottlenecked on your 3080 GTX even with many fewer CPU cores. 5900X is a workstation-class CPU.
