I play video games a lot and my current MBP with a nvidia 330m just doesn't cut it these days. I've considered buying a cheap PC laptop for gaming but I really want the retina display. My girlfriend plays games with her retina display MBP and it blows my mind. Would you consider the new Haswell MacBook Pros an excellent option for laptop gaming? If not, please state alternatives. If so, please explain why. Thanks!
