Which one should i upgrade first? i want this update to allow me game without worries at least 3-4 years.

I'd say go the motherboard + cpu route, but you'll also need a new kit of ram since your old socket mounts DDR3 and you can't use them on the new one

Thanks, i know, is the most expensive upgrade. that's why i'm not sure if do it first. 
If i pair my FX with the RX 5600XT. Should i get a big bottleneck?

after that upgrade to 5600 XT. keep that ips monitor. IPS is the best panel out there. 1080p 144hz ips is pretty good

The IPS i have right now is only 60Hz and 4ms. I want to buy a TN 144hz FreeSync 1ms for gaming.

Since your goal is I'm assuming to even utilize that 144Hz monitor then buying either a new GPU or CPU won't benefit you in any way since the FX 8320 + R9 380 can already achieve above 60 FPS in DOOM and because your monitors are 60hz you won't notice a difference, I would go with the monitor upgrade, and then CPU and then GPU.
 

I would also suggest to hold off on the GPU upgrade and wait for the new GPUs to come out this year.

Yes the FX 8320 would bottleneck the hell out of the 5600XT, you most likely won't notice any performance improvements over the R9-380 if you do so.

Monitor upgrade should be the last thing you do tbh, unless you upgrade everything at the same time, since with your current CPU but a better GPU you'll barely see any gains, and with a new CPU will get something extra from your GPU but not enough to justify a 144hz monitor.
