Hello all, I wanted to get some opinions one what parts are most important to upgrade for improved workflow and video preview for video editing applications like sony vegas. Basically I edit bluray video for amv's (animated music video's) and my preview window and basic workflow speed can be choppy and not quite as smooth as I want it to be. Does CPU have biggest effect with this kind of stuff (and if it does, would you suggest a hexa core CPU or would something like an i7 4770k quad core CPU be enough for editing bluray footage)? or is computer RAM important? I also heard that Doing something with your hard drive can have a greater effect in improving these things. Any thoughts appreciated! Also, assume money isn't a factor, just want what performs better.
