Okay so i have posted here a few times about crossfire and asked question but people say it just cause problems, what are these problems, can someone explain the problems and list. cause when i ask the person they just say problems. Planning on cross firing 7970's or 280's.
What problems can Crossfire cause for computers

The largest issue is a thing known as micro-stutter. See here for more info:

Of course, these configs also use more power and generate more heat and noise (typically) than single GPU systems.

Crossfire, like all multi-GPU solutions, can cause issues like microstuttering and dropped or runt frames.
Microstuttering is what happens when you get sudden changes in the framerate, usually dropping from a high framerate to a low framerate for a fraction of a second, then going back up to a high framerate. This affects different people differently. Some can barely notice it unless it is really pronounced. Others are very sensitive to it and I've seen people claim that it can make them sick and nauseous.
Dropped and runt frames are basically when the GPUs fail to correctly render frames, causing the display to essentially skip over those frames. This can be perceived by the player as stuttering or hitching on the monitor.
In the past the issues listed above have been huge problems with crossfire, which is why I think many people, even today, continue to be turned off by even the mention of crossfire. But newer AMD drivers have largely fixed these problems. However, I still wouldn't say everything is 100% okay, and from what I hear crossfire still isn't quite as good as Nvidia's SLI.
Another potential drawback to crossfire is that not all games scale well with it, meaning that you don't get the full power of that second card. For example you might get only 50% better framerate with crossfire over single-GPU instead of the theoretical 100% gain you should get. This can be mostly fixed with driver updates, but AMD has been known to be rather slow about releasing such updates. But again, word is that they are getting better at it.

the newest amd beta drivers, have fixed microstutter in a few dx11 titles at resolutions 1440p and lower. for triple display there are huge issues, and the same old microstutter issues in dx9 games.
