hi i want to buy this gpu https://www.asus.com/Graphics-Cards/MINING-RX470-4G/ but i have heard some people saying that these gpus can't be used for gaming and stop working after a while because they are optimized for mining and only have 4 mosfets while gaming gpus have 6-8. i also guess that im gonna have to install a gaming bios on the gpu to use it for gaming. are these true ? and if so, should i buy it or not ?
