Hi all. After a little info / advice please. I've been a pc user for years, and dabble in a little video editing etc. I recently bought an hd video camera that records in avchd. My current pc - quad core 6660 I think it's called, 4gb ram and a 512k video card just doesn't hack it. So I'm looking at upgrading. I seems for the same price I could get: iMac quad core i5 3.1 4 gb ram, 27 inch, 1gb graphics Dell or custom pc, i7 8/16gb ram, 1gb graphics. I have some mac fans as friends and they say a mac runs faster than a pc. My concern is if I buy mac I'll be buying almost the same spec as my 3GS old pc. Are they that much faster? Also went into apple today and they couldt get my sd card with .mts files to work on a mac. Does anyone here do video to answer that? I've never looked at a mac before, but now have iPad and iPhone and love they way they work. iMac I assume I'll be just as impressed with but do wonder if they really are that much quicker that the 2 specs above are an equivalent speed... Any info / advice appreciated!
