>>32617amazon gave me a price 339 dollaridoos for the 3800x, and 399 for the i9-10850k.
In case you are not familiar with the chip itself, the 10850k is the 10900k rebranded and sold for a lower price. This means 10 cores (instead of the 8 in the 3800) that can clock to 5.2 GHz stock turbo, given thermals and power. You are getting the top tier IPC that can be only beaten by the currently largely unavailable Ryzen 5000, which won't get a successor for a long time from now anyway, and AMD went full intel on the pricing and bumped it high.
Cooling and the added cooler from the ryzen is literally a non-issue for our household schizo since he has a large aircooler in case you googled his part number
If case you are hellbent on PCIe 4.0 support, the coming rocket lake will be compatible with Z490 motherboards and many if not most of them were already engineered with PCIe 4.0 in mind
But the top tier rocket lake sku will only have 8 cores unlike the current ones since they are gunning for IPC, so with the 10850k you get the best productivity score as well as probably the best investment in future since for example cyberpunk2077 is already behaving badly on less than 8 cores (5600x being the only exception) and this will only get worse over time, so more cores are better if you want to keep using your computer for a lot of time
Memory. The endtimes for DDR4 are already here, companies are already announcing DDR5 in the serverspace, so you can wipe your ass with your X570 when there will be a generational RAM change anyway, and the 5000 series uses the memory controller of the 3000 series, so you are locked to 3600 MHz anyway
Fun fact: the 5600X costs the same in my country as the i9-10850k
pic related is how the PCIe 4.0 equipped gigabyte boards look like
GPU passthrough is a use case I didn't look into, so you might be right there. Of course if that is a killer feature, you are right.
