Currently, I am hashing at around 33mh/s at the following settings +13mv, +10PL, 1180Mhz Core Clock and 1500Mhz Memory Clock with temperatures not exceeding 75 celsius on all my GPUs (Open Rig... Oh and the last GPU3 value is for a regular 390 without x)

My questions:
1) What are the best OC settings for R9 390x for the maximum Hashrate? (I own Sapphire and ASUS GPUs and heard that they can get up to 35MH/s)
2) Does OC decrease the lifetime of the card? If yes, does it have a really big impact on its lifetime?
3) How long is the lifetime of a regular GPU mining 24/7 with good ventilation, regular fan oiling and dust cleaning
