Just follow it, these make sure that you install no software that can be causing problems.

I wouldn't understand why you would get a new card while a BSOD hasn't occured in weeks.

That is what I'm saying, the atikmdag.sys/atikmdag.sys drivers are AMD display drivers, these drivers are one of the most frequent causes of BSODs. Normally at least 3 different drivers needs to be tried before we should move on to checking the temperature what is done by stress testing, checking if the GPU is improper seated or damaged, if it receives enough power, if it is overclocked, etc.

The difference with the previous suggestion is that I've now included a tutorial in which is explained how to install drivers only.

Yes, I let that choice up to you, I'm not familiair with any driver that could be stable
Maybe this link helps?
