Cheaper board, and the K version CPU.
I imagine you don`t want to OC, but this build is cheaper than the one you had, so please, do me a favor if not for yourself, and get the 6 pounds more expensive K version.
At one point, you might feel the need for a stronger CPU, and you`ll just be able to OC this one, in stead of replacing it.
The rest of your build looks great, I`d love to see some pictures of it once it`s done.
