I bought SuSE 9.0 Personal, and have been very happy with it so far (and I'm a total newbie). The only 'problems' I've had so far are:
a. The k3b cd writing program isn't working properly, but I have established there was an oversight with the compilation of the version that was shipped in the package - haven't done anything about sorting that out yet though.
b. My wireless adaptor (D-Link DWL 120) doesn't work out the box with this distro (and all the others too, I'm led to believe). Have been trying to sort that out, but so far without success.
With YAST I have upgraded my kernel successfully.
I can't comment on Nvidea though.
