I have both CPU board - one is 1.25 which is overclocked to 1.58Ghz , the second is 1.33 which is overclocked to 1.5Ghz - the differences between those two CPU board is only L3 Cache . 1MB->2MB , after overclocking i checked Geekbench scores for that CPU board and the first one achieved 960points the second 940points. So it is not a big differences.

amigadave - definitely you should try MOS 3.12 on your machine change the graphics card to x800xt or better, put SSD and finally change fan to quieter version and MOS will be flying
