Hello! Please, need an advice. I have an ability to buy a used MacBook Pro for video editing. Configuration: MacBook Pro (early 2011) 2.2 GHz Untel Core i7 8 Gb DDR3 AMD Radeon HD 6750 1024 Mb Now I'm editing on windows notebook: 2.4 GHz Intel Core i5 8 Gb RAM AMD Radeon HD 7470M ...and it's going quite slowly with fullHD footage. Is there a sense to change my Win-book to this Macbook? Will it be distinctly faster? Thanks in advance!
