Yeston only has a 6 month warranty on GPU's so that doesn't say much for long term expectations, also forget about customer service if you live in the US. I had a RX 580 GameAce sent to me from a friend in China, I ended up reflowing the solder right out of the box since it looked like a "What not to do" in a basic electronics class. The PCB of that card was underwhelming even with 3 fans, for basic use it ran hot as hell and you could forget about overclocking at all, we ended up customizing a water block for it which dropped normal temps by nearly 20 degrees but it still would not take much of a overclock. Drivers were another issue, it worked better with generic since theirs were unstable.
