So, this question might have been asked very often, but I still haven't found an actual answer.
Is it worth buying an engineering sample CPU off of ebay? I've seen a nice 9900@4.40GHz for 290$ with free shipping. (https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.de%2Fulk%2Fitm%2F153792563829)
Also, would the MSI Z390 Gaming Plus support this chip? I don't really plan on overclocking (I heard they OC better so I might try it), but I'll surely lock all cores to 4.40GHz in throttlestop.
Now, by looking at performance, I know it's basically a 9900T eating up 65W instead of 35W, but it still costs less than a 9900T.
