Simple question: what's the point of DDR3? No one will gain anything, especially on a fifth-generation ASUS (I'm talking about the motherboard), so my conclusion is that this configuration is a bit absurd. No one in their right mind would install DDR3 today (unless they have a lot of money).
Dear Hero In, that's your opinion, and it will remain with you.
P.S. Please, don't address me in the plural... "You" is capitalized.
