Futuremark pushes the gpu too much, I would try 3dmark instead.
I'm guessing you are referring to "furmark" (I'm only guessing though ) and I'm not really sure that's the case with more modern GPU's. The benchmark programs push the GPU to 100% and hold it there for a period of time, that's fine, its 'normal use' for the most part. The issue folk seem to have with the likes of furmark is that it holds the GPU at 100% for an extended period of time. I have not heard too many horror story's from the folding@home world of folk melting their GPU's through doing that and that requires 100% GPU for extended periods too Maybe I wasn't looking hard enough though.
However saying all that, I actually meant 3D mark not futuremark . I'm offshore at the minute and cant load the website, but if you google 3dmark you'll find it no bother. Also there is a PCS forum for posting the score too https://www.pcspecialist.co.uk/forums/showthread.php?8328-Benchmark-Results-Leaderboard

I'm reinstalling the game, I'm just hoping that my Cities of Tomorrow expansion still works!!
Surely that will just reinstall with the rest of the game?
