OK, so I've waited long enough to finally get myself an iMac. I went to school for film, and have been out a couple years getting myself on my feet and saving up some money. Ultimately, I'd love to get myself a nice PC and a Mac for a video editing station. First comes the Mac. I've been researching tons, and find bits and pieces of info that help me in my decision, but I figured I'd reach out to a couple forums. Keep in mind, I'd like this Mac to last a decent amount of time for me (or as long as I can with technology quickly moving along). I don't want to skimp on something just for a few hundred then a couple years down the road wish that I had gotten the other option, so I'd rather suck it up now. But I don't know what is necessary for what I want and what is not. I'm going to use the system mostly for editing purposes, so it's going to need to be able to handle lots of footage importing, rendering, storage, etc. I'm most likely going to be getting Final Cut X (please don't turn this thread into should I get that or not topic) because it seems like Apple is sticking with that new format and not going back. (I might also get an older version of Final Cut just to have). Not too familiar with the specs of the new FCX either, and how it works the iMac system, but I want to be able to get the most out of my system. I do know that I definitely am getting a 27", I'm not made of money so unnecessary options should get weeded out. When capturing/editing/previewing how much difference should I expect with an i7 vs i5? Did anyone get the AMD Radeon HD 6970M 1GB GDDR5 vs the 2 GB and regret it? If I get the 4gb RAM, and want to upgrade with another 4gb myself, will it void out the warranty? Also, will the Mac come with the additional 2 slots needed if I wanted to do that myself? For those of you in my situation, what did you go with and do you have any regrets or praises? Sorry for the novel, but thanks for the help! tl;dr.... I want to get a 27" iMac for video editing purposes... what system specs would you recommend without breaking the bank with unnecessary hardware?
