I agreee to a certain extent about the price and mentioned in the review that the board should be priced around £20-30 cheaper. However, this is new technology, albeit slightly inferior in certain sectors to older X58 chipsets and because of that the price is inflated accordingly. I couldn't really put the price as a 'con' as it is pretty much inline with what other manufacturers are charging for a flagship P55 motherboard.
The jump between the two technologies is indeed nothing to shout from the rooftops about but the performance difference is there. How much you value that extra performance will depend alot on how much of an investment you see a PC as.
As always guys I appreciate constructive criticism and feedback, these are afterall - reviews for YOU!
