Sorry to hear about your woes. I think I've had some Asus kit and not had issues, but I've not built a PC in a while. I was never into graphics cards as I'm not a gamer or miner. A good company needs good technology and active support to deal with any issues and it looks like they slipped up on this. Maybe you were unlucky, but they should deal with it promptly. I guess they think they can afford to lose a few loyal customers.
