I costume build my computers, also 'Apple' and 'computers' should not be said in the same sentence it's blasphemy
Apple has been making 2 processor computers for a while now, and I'm sure many other companies have. There are probably motherboards with 2 processor slots.
Probably costs 12,000$ being it's from apple.
my server computer had 4 processors :I
I hope you were using it for a shared server. It would be overkill for anything else.
