Well it's time to look at updating my rig as I my current ESXi white box server is no longer able to cope. So I am going to upgrade my main gaming rig and then use this's mobo and CPU as the new ESXi 5 box

Anyway this means that I will need to get a new Mobo and CPU I am going to get the 2600k i7 but I am not sure around which Mobo to get I was thinking of getting a nice ASRock Z68 Extreme4 Gen3 but have seen some mixed reviews so wanted to try and get some thoughts from you fine people.
Many thanks in advance.
