Well, I have the opposite opinion. I tend to prefer AMD over Intel
and the main reason is the amount of power the systems eat and the
amount of heat they produce. I'm sure everyone has their favorite
horror story about melting down cpus, but in the last year I've blown
up more Intel systems from heat then AMD (one Intel and zero AMDs,
which means nearly none of either), so I'm not inclined to buy the
meltdown argument. Intels do not gracefully degrade as well as Intel
would have you believe! And my AMD boxes are no more or less stable then my Intel boxes, so I don't buy the stability argument either. I would love to see AMD be more proactive with regards to opening up the chipset support, but that is pretty much my only complaint.

    Equivalent AMD systems are certainly not twice as expensive as Intel.
    The premium is typically less then $100, usually due to the MB and a
    slight premium on the cpu, but that's it.

Matt, I am not defeating AMD either, its CPU is really cool, I just
does not have confidence with its chipset strategy, I have very bad
experience with NVIDIA chipset and obviously it is best praised
chipset in AMD world, when we are talking about platform,
it is not just about CPU, in most cases, chipsets and other supports
are more important than CPU. I just heard even if a NDA license
is impossible from the chipset company. If anyone can make my
nForce 3 ultra network adapter work in BSD world, I will appreciated
it, current I have to insert a very cheap realtek 8139 into PCI slot,
I wasted my money on NVIDIA, this is rather annoying.
