Alright, by changing my GPU's max power to 105% I get 10k furmark at least, with max 78 temp. Should I use 105% ?I've never used UserBenchMark to tell me if is right or wrong with my system. Tax your build with the app's and games(if this is a gaming build) and see if you're seeing hiccups in said build. Likewise you can use benchmarking app's like Superposition or in game benchmarking tools and then pass on the screenshots to said benchmark runs.
UserBenchMark also doesn't state the make and model of your PSU.
It looks like there is a driver update for the gpu.
