Pros and cons??

Id debate 3X as quick but certainly with the i7 build you're much more likely to have a future upgrade path, with the 775 you'll have to bin everything and start again, and the mobo is ****

Thanks for all the comment, appreciated. With regard to the motherboard, it was a shot in the dark and chosen as it was the cheapest option with 6 ram slots. Is there a better option close by in the price range that would be recommended?
