Hi mate - obviously you might think my opinion is a bit biased as I'm selling the bits but the i7-4770K quite comprehensively out-performs the AMD across the board. It's also a newer manufacturing process, runs cooler, draws less power, has built-in GPU (if needed) and a few other benefits too. The motherboard is also towards the higher-end along with the RAM and the parts were deliberately bought to compliment each other. I would happily have kept this system had an unexpected upgrade not tempted me! By all means please feel free to seek opinions or check out the specs / benchmarks for the components I'm selling; they are good quality components :smile:
