If you are doing video's then get a dedicated graphics card with a good amount of cuda/stream cores.
OK,have to check more on that subject, but tell me do u have any experience on that?
Is it faster than 2600K CPU? Or does it free the resources on the PC so u can have it run in the background and do some photoshop without decreasing the quality of the video task?
Does it make that much difference in time? I could use it.
