I see im not aware of these issues so thankyou for the advice. I'd definitely prefer to go intel so ill go with the 245k then as its a similar price, is newer and I really want to try the latest components.12th gen is safe to buy, but I wouldn't buy a 14th gen CPU anymore, not after the degradation issues. The 14600K should be less impacted than the i7/i9, but I still wouldn't buy one.
The 245K and 265K were heavily discounted awhile back, so if I was determined to go Intel, that's what I'd buy instead.
AM5 has hopefully got a better upgrade path than any of the current Intel sockets.
So I know im now looking for a 1851 MB, I know I want to go pcie5 and ddr 5 and have integrated graphics. Any suggestions?
