iMac 27: Was I wrong?

Hello, I need your kind help to get my sleep back )

I am a photographer, I also dream to do some graphics in the future, and occasionally might work with video montage too. I buy imac for my own money and i hope for it to stay with me for a considerably long time.

I just bought imac '27 2.9 basic low-end configuration few days ago. Now i started to think more often that I made a mistake and the imac 2.9 is meant for "office users" who prefer big screens, while iMac 3.2 with bigger graphic processor is meant for photographers and designers.

Some reviews say you might get a better result if you chose 2.9 imac and add a fusion drive, will this make my 2.9 imac better than 3.2 imac without a fusion drive, considering that my graphic processor remains to be 512 mb and can't be updated (not like 3.2 that can be updated to 2tb. But I wouldn't run very fast to do it, because I just probably don't need it? It's just about having an option). I am a new user, when Apple says about update, they mean straight away update, not a later update by buying smth, i know it's possible for RAM at 27 macs, but fusion drive and graphic processor has to be installed from the beginning or no?

I have a week to return the computer, and pay 200 dollars more for another version. Should I do it?

Thanks a lot for your help....I am really lost now... and start loosing my after purchase happiness for a sadness of a hard choice again...

 

Raima, thank you very much for your reply.

I am trying to be happy and there's a reason to be. I've got the computer I was looking for But as I am a new imac user and not very strong on the technical side I am trying to be sure that i don't actually miss anything...

I can install fusion drive only when i buy imac, not later.. is that right?

Another point for getting a high-end one is it will be be probably easier to sell 1 gb graphic processor in few years... or maybe it will anyway all be outdated....

At the same time photographers work on 21.5 imacs with have the same graphic processor parameters and they are doing just fine...
