i'm going to be using this in a very consumer way -- no heavy video editing (although i will be editing HD home movies) i am about to pull the trigger on the 24" 2.8ghz iMac (my first Mac!) simply because it's a lot cheaper than the new updates any reason why i should jump at the chance to pick up the new video card? i will be upgrading the RAM to 4gigs after i get it if i'm editing HD home movies and exporting them to iTunes for my AppleTV, am i going to wish i had the more powerful graphics card? i'm coming from a pentium4, 2.66ghz, 1gig RAM machine that's 4 years old . . .
