Nope--I've been using an NVidia graphics cards (not built-in) since 2003 without issues.
How did you do that? i tried an old NVida GeForce 2 (out of the 90's!) with a legacy driver, and OpenSUSE did not enjoy that one bit.
It turned out that the Neuveau driver worked just fine (including 3D support!) without trying to install the legacy driver, but trying to get the legacy driver to work made me nuts for a while. Never did succeed to get it.
