Dual ASUS R9 280X DCUII TOP with 650W PSU
I am going to be mining with two ASUS R9 280X DCUII TOP graphics cards. I already have a 650W Superflower Golden Green PSU (80+ gold rating). Clearly I'll be cutting things fine to run this setup, but do you think it's possible? What risks am I taking -- in terms of damage to the graphics cards, overheating PSU etc.
