i use AMD and NVIDIA in my machines and i don't even care about using the latest driver unless there are TANGIBLE benefits and its stable in my system. meh, maybe that's just me...
NVIDIA releasing new game drivers (i.e. witcher3) is more of a marketing move as they didn't help performance. hell if I was AMD I'd do the same. crono cross had good music no doubt but that's a given for golden age square...
