Been working on this issue at home for about a week now with no real sucess of getting my card to run various benchmarks and games with full/max performance. Core Mhz, core volt and gpu usage keep going down and up, too many fluctuations and not stable. Forcing always maximum performance would work sometimes and this was with 2 or 3 driver releases ago, now doesn't work. For some reason would still downthrottle the core Mhz, volt and gpu usage. Tried all kinds of fixes from other forum and experienced memebers and I'm almost giving up. Last thing I will try tonight is re-flash stock firmware on it test with older drivers and see.
