is crossfire reliable?

Answer 1

What's your definition of reliable? Is your definition is whether it simply works all of the time? Then the answer is yes. Is the definition that it always is faster than a single card? Then answer is "it depends", some games actually go slower if Crossfire is being used. Most games just ignore it, so it may or may not result in faster performance. AMD has stopped supporting Crossfire in its cards. It doesn't mean that they won't work, just that there's no support for it anymore.

Answer 2

Yes amd crossfire is reliable just make sure the card supports it and you have the things necessary to do it

Answer 3
