Linux Kernel Archives or ELRepo

Hello All

I am currently working through my RHCSA and RHCE and ive purchased red hat 7.4 workstation, my only issue with it has been that the kernel and xorg don't want to co operate with my nvidia drivers, ive troubleshooted till im blue in the face and haven't been able to get it to work automatically with the latest release kernel from redhat.
If anyone would like to give their 2 cents on it ill post the link to the thread i created for it.

As a workaround ive used the lts kernel from elrepo which works as expected but since im learning to build rpm's etc im considering compiling a custom kernel for my machine from the linux kernel archive just as a learning opportunity.

Can someone please tell me if there are any caveats or precautions i should be aware of ? or for safety reasons am i better off with elrepo if i need a non official kernel ?

Kind Regards
