the y50 is more light and thin with olny 0.9 inch thickness and the y50 have an JBL subwoofer at the bottom of the laptop. the y50 also have more ventilation for better cooling.
well the lenovo y50 is great at cooling because it have 2 fans. 1 for cpu. 1 for gpu. the msi ge60 2pe apache pro olny have 1 fan with cooler boost which is very loud when it is under load.
