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.
