Lenovo Y50-70 Laptop for Video Editing

This is a cheap laptop with a 4K screen that Im trying out for video editing. Its cheaper than my Macbook Pro but for a reason.
The old myth about PCs beeing cheaper than Macs is still going strong but it is just as false today as it was a few years back.
A PC with the same specs and quality as any equal Mac costs a fortune. But if you are ready to be extra carefull, can stand some corners beeing cut a low cost PC is a good option.
