Sorry for fishing for your suggestions in making my purchase, mates, but I need your help and expertise. I am looking at getting the 21.5" iMac, but between the two I am trying to figure out if it'll be advantageous for me to spend the extra $350 (educational discount) for the higher end 21.5" with the 6750M card and extra 500GB hdd. The 0.2GHz processor boost will most likely not be noticeable at all, so therefore isn't inclining my decision; I am mainly looking at the 1TB hdd option and the difference between the two 6750M and 6770M graphics cards, but I sadly don't know a lot about gpus and couldn't really find anything at all online as far as comparisons between the two.
Main uses for computer: Final Cut Pro for HD video editing (not heavy into video); Logic 8 for music; Adobe CS4 (pretty big into photo editing) and just basic stuff other than that. I may play games down the road on it too.
So, basically, I do probably need the 1TB hdd (for photo alone), but and mainly looking to see if it would be justified spending the extra for the better graphics card and 500GB extra hdd space for me, or if I would be better off saving that money and just buying a 1TB internal and installing myself - saving $250. Is the 6770M THAT much of an upgrade? thank you for those that took the time to read, too; I'm trying to be a thorough as possible.
