Hello I wanted to know what the difference is between the two because I'm planning on buying a video card and the thing is that the armor one is 387 euro whilst the gaming x is 450 euro, I wanted to know what are these 60 euro different ? are we talking about 10-20 fps or just little fps like 1-5 ? Which is better to buy ? can it cause small overclock issues the armor ? must it be updated on bios or anything?
