I have a HP Envy 13 Laptop and want to buy Hitfilm4 Pro. As far as I can tell I meet all the system requirments, only with the graphics card I can't tell if it is up to the task, as I have to admit I don't know too much about this stuff. I use Express and for the most part it seems to work fine. But before I spend 350 bucks I want to be sure I can actually use it. If I do need a better graphics card what should I do? I read about some ''graphics amplifiers'', but don't quite know if that would help, if they are compatible and worth it. I'll be glad to answer any questions. Thanks a lot!
