Signs of bad SLI drivers?

[Shamshir]

I keep hearing about the disadvantages of SLI, one of which is bad drivers. So, what are the symptoms of bad SLI drivers? Poor performance? BSoD?

Would appreciate any help, as I'm currently troubleshooting BSoD's that I think are related to my two GTX 680s.

My experience has just been poor performance. Never had a BSOD or the like due to them, maybe im just lucky. But thats my experience
