It is worthy to replace my Graphics Card?

Hi All,

I have and old Pc that I think is still useful if I make some changes. Actually the pc have and Intel Core I7, 16GB RAM, SSD 1TB, but the graphics cards is very old ‘gtx550ti’. I have checked the compatibility of my mother card GA-X79-UD5 with a gtx1660 ti and it is possible to upgrade it. But im not sure if I will get the full potencial that the 1660ti can give me. Do you think it is worthy to try an expansion?. I just would like to play actual games without build a new pc…thx
