Help with choosing imac

Hello everyone,
I am new to this forum and also new with imac. I have used it in a past a bit but newer owned one before. Recently I decided to buy imac since my pc is too old and since I use other apple products I decided for imac because I am not big fan of laptops.

The problem is new 5k imac which messed up my plans a bit
I was almost sure that I want late 2013 3.4 i5 8gb Ram 1Tb HDD or fusion drive imac. But since 5k was released I really can't decide.
Saving money is not priority but I really can't go over 2.500 eu because I am casual user, and not professional. I mostly use it for internet surfing, playing movies, a bit PS, word processing etc.
So the question is, is the new 5k model worth it because I couldn't buy more than base model 5k. Is maschine good enough for that gorgeous display. Or is it better to stick with last year model and save a bit. Which one is better and longer investment for someone who is not demanding user, but still appriciate amazing display.
Thanks in advance.
and sorry if my english was not good enough, its not my native language.

 

Thank you for your responses.
Even though I know I don't necessarily need 5k display, I want the best solution I can get for amount of money I have. And it helps to hear another opinion.
My only problem was, like I said, because I can't afford more than base model . And I only read about experiences of people who bought upgraded ones.
Because I am not a computer specialist, I can not say from specifications, is the base model good enough for that kind of display. If I could be sure its good enough for my needs, which I already said, are not big at all, I would buy it without hesitation. I am not someone who change computers every now and then, and I want something with what I can be satisfied for a couple of years. If that is base model 5k then I already have made my decision
