Yes, same here for AMD. I bought it because it was more affordable and so is mainly all that I am familiar with.
As for 3D effects, I am impressed with Intel, or at least their on-board graphics, but this is from impressions from hardware from about 4 years ago and may also have to do with on board chipset type. I read lines like this from nVidia wiki"The proprietary nature of Nvidia's drivers has generated dissatisfaction within free-software communities. Some Linux and BSD users insist on using only open-source drivers, and regard Nvidia's insistence on providing nothing more than a binary-only driver as wholly inadequate, given that competing manufacturers (like Intel) offer support and documentation for open-source developers, and that others (like ATI) release partial documentation and provide some active development"
But, this is only one source and one opinion.
I have wondered why Intel does not make video cards.
Recently I had problems with Plymouth boot up graphics in another distro and it had something to do with nVidia proprietary drivers not supporting KMS. I guess these problems are solved over the long run, but may be not or not soon enough. I'd rather go companies that try to work out Linux solutions.
