So I edit mostly 1080p DSLR footage taken from my canon T3i camera. I purchased a 2011 (the latest model) iMac a little over a year ago, upgraded the RAM to 12GB and it has worked reasonably well. I purchased the base model for $1200 which has a quad core i5 processor, 512mb of video ram, and a measly 500gb hard drive. The past couple of days I have come to the realization that I only use Adobe Programs for graphically intensive work (premiere, after effects, etc). I originally bought my iMac for final cut, but FCPX SUCKS and I switched to Premiere CS6 which works like a dream. Anyways, I'm a senior in high school and do lots of video editing (going to major in video production in college). I'm likely going to differ college for a year and continue my video production business (pretty informal) as well as video production internships at a couple companies (so don't suggest that I get a laptop for portability, not an issue). I just shot an entire wedding with 2 DSLR's and the footage takes up over 20% of my hard drive which is unacceptable. This is very troublesome for me and has been clogging up my computer considerably. I have realized it would make a lot of sense to sell my iMac and purchase a PC that's not only faster, but has much more space. I was ideally looking to sell my iMac for $1000, and from that get a better and faster PC setup for my video editing. $200 would be allocated for a 24" 1080p LED 5ms Asus monitor (from newegg) which would leave $800 remaining for the PC. Ideally it'd be nice to have a little cash left over. Some things that sound appealing to me are: an intel i7 quad core proccessor at least 3.0+ Ghz, 16 GB of ram (maybe 8 to start), 1 GB of video RAM (here is where I'm stuck, my Imac had a Radeon 512mb video card in it, but I've heard premiere runs especially well with nVidia CUDA cards? Don't really know too much about this stuff.) I have no idea what type of card to get, and if I would even see a performance upgrade from my iMac. For storage I'd like at least 2TB of space, should I get two seperate 1 TB drives? One for boot and software and another for video files? Anyways, I assume I can benefit from selling my 2011 i5 iMac to get a faster PC equivalent at a lower price since I mainly edit videos (which is pretty graphically intense) from an HD DSLR camera. I've noticed premiere rendering times on my mac are starting to get pretty slow these days. Ideally it'd be nice to buy a desktop (already assembled) maybe from HP for around $600 (not including the monitor). I'm not completely against building a PC from parts (since I know a friend who can do it for me) I just need help figuring out WHAT exactly it is that I need and would benefit from.
