Oh oh...............I´m surprised u still working with R7
. Indeed there is a significantly development from R7 to R10.
The mainly thing is that you get more and more troubles with newer cards from the community concerning missing or outdated mods.
But as I´ve seen here you are more on making your own stuff, and your cards created in R7 should make no troubles to your fans with a newer version for now.
Anyway if u decide to upgrade (recommended clean new install) - I guess there is a R10.1 coming soon, so better u wait some weeks more
