Thanks a lot Greg, I did notice that RAM were so expensive with Apple like 500.00$ more if I want 4 GB instead of 2! Thanks for mentioning where to look. And thanks for the feedback on my gallery :)

And it's also good to hear that Vue runs fine on the iMac, that it wouldn't be a poor choice as it was one of my concerns, I'm really glad you mentioned this.

Really helpful info, thanks a lot, I really appreciate it.
