ok I will be looking at getting my first Imac but what should I be looking for is there A model in your opinion is better than the next. I would want it for going over my photos since I just got the Canon 5dmkII but which model is worth the buck and which is just over kill ? Let me know what in your opinion is the perfect setup one with massive storage , fast graphics 1 or 2 gig? how much Ram is needed ? Well hope I don't buy something that is just overkill and spend too much ..thanks for any help I usually just play starcraft and check the email , surf and now play with the pictures and aperture software I hear that really slows the machine down ? soo many questions sorry.
