Yeah, in South Africa the 5900X is $163 more than the 5800X and the 5800X is $209 more than the 5600x.Are they? the 5900x in my country is 125€ more expensive than the 5800X. I think the 5800X may not be the sweespot in value but I think is the best choice if you don't want to break the bank and have a CPU that will last until the mid of the decade (if not more).
The 5950X is a whopping $393 over the 5900X at the current exchange rate ($1=R15.25)
I went with the 5800X because it has 8 cores(16 threads) like the consoles and because at the end of the day PC parts in SA costs a crap load more than they would if I lived in the US.
I literally paid $2242 which is way more than I would have if I bought the same in the US.
I had a look for the same parts in the US and could have bought all for $1898 and a difference of $344 or R5246 in South Africa. With that money I would have bought a 5950X.
In October the Exchange rate was R16.25 so it could have been worse.
