Hello

I want to buy a new desk top
I selected two models
one is fitted with a GPU NVIDIA GT520 , Price : 700 euro
The other one with a GTX 560 TI , Price : 1000 euro
Both cards support Direct X 11
Same INTEL CPU , RAM memory , and HD

I wonder whether it is really worth while spending 300 euro more just to have a GTX series rather than the previous GT

I realize of course that , up to a certain extent, it is a matter of taste
But my question is

Can you really appreciate the difference in a real game ?
I am not interested inn benchmark tests

Thanks in advance
