Well, if you're planning on getting a new motherboard, you should get one with GMA950 as it's the only graphics card that work without any patches. Any Nvidia or ATI needs natit or titan (driver) to work.
As for the best supported (but not without patches), I'd say the Geforce 7300GT, 7600GT, or ATI x1600.
That's not really true, you need to remove some kexts to get res change on 950 - but it's academic since it sucks arse and you'd only want to use it if your real graphics card catches fire. Most 7xxx series card work without problems, those with ram bigger than 256MB require a bios flash. Whatever you go with, you will either have to install natit et al. or tweak your system in some way.
