I know it's a bit of a n00b question, but it's been sitting on my mind for a long time. When I first started proper editing, I had 4GB RAM and I was able to edit 1080p video just fine, managing FCE4 perfectly and even Premiere Pro and After Effects. I soon upgraded to 8GB, and I don't know if there was even a difference, I didn't feel as if I could run more programs either, the 4GB seemed to be good enough at running so many programs. However, I was definitely able to do longer RAM previews in AE. What's more important in video editing; getting more RAM or getting a faster processor? Where does RAM even make a difference when video editing? And, with today's software, what's more important, CPU or GPU? I've been reading around and people keep saying CPU, but they appear to be older threads before we had so much 'GPU accelerated' stuff. Perhaps they're outdated, but I saw a thread from last year where people were agreeing that a CPU will do better when working with video. I was arguing with my friends earlier today about how video editing is [apparently] more CPU intensive, but they kept on with their belief "No, all video is done in the GPU" (They definitely don't know much about video in general, I told them their belief is built on gaming - Something to add is that they think FW800 is outdated and that Thunderbolt is a 'crappelised' version of USB, lulz, no idea how you could act like a computing warlord and have no idea what Thunderbolt is) Edit: Don't take me for a n00b in other threads though! Sometimes I like to check over things to make sure I am actually correct, regarding RAM though, I'm taking this from personal experience. And, regarding the CPU/GPU dilemma, if someone could explain what actually goes on, that would be cool.
