He can buy a much better motherboard that supports newer processors for less than you can find that one for. I was considering recommending either that one or the one that supports socket 939 because he can carry over some of his legacy hardware, but socket 775 and 939 are as dead as the what he is upgrading from. Better to go with an AM3, or LGA 1156 motherboard and if I was starting fresh knowing what I know now, I'd go for an LGA 1156 and G6950 or Core i3 with the object of eventually upgrading it to an 800 series i7 since they are less CPU bound in games than Phenoms. LGA1366 motherboards and i7's are just too expensive. I would have paid more for a motherboard and CPU than I paid for my whole system if I had gone that route.
