I'm build a Windows gaming machine for my other half for Christmas. While the primary purpose of the machine will be Windows gaming I'd like to set-up with a dual boot Linux OS. I'd like the cards 3D functions to be supported with an open source driver when running Linux.
As my other half is unlikely to be playing super hardcore 3D games requiring the latest/greatest GPU I think I can afford to run a slightly lower spec card to get Linux support. I'm assuming that Intel chipsets are still non-competitive for gaming setups.
Which family should I choose, ATI/AMD or nVidia? Does ATI/AMD have an advantage over nVidia as novoue is completely reverse engineered versus some info available for ATI/AMD?
Card suggestions welcome.
