620 to a E5. Should I ??

Seeking a little advice/point of view. The short: I have a 12-60 & a 50-200 and an E620 I am considering stepping up to an E5. The E5 of coarse more $$ but also more features. Features not that interested in, at least for me at this point and time. I just want to shoot stills. Do some of you that had E620’s and stepped up to the E5 feel it is a worthy upgrade just to do stills? Keep in mind with me it is a hobby with me but still feel at times the 620 is not giving me the results I crave. Especially when looking at other peoples work using the same lens that I have. Don’t get me wrong I still love my 620.

Thanks for you input
John
