On a price/performance basis, it's clear that AMD beats Intel at every price point. You should know that both Intel and AMD ship firmware blobs for their CPUs which are redistributable but not open source. > 2.

MSI, Gigabyte and ASUS, at least, sell extended-ATX motherboard with sufficient room between x16 slots to fit 3 double-width graphics cards. You may have trouble finding a suitable case. The AMD cards probably don't function without a firmware blob, even with otherwise open-source drivers. -dsr-
