So, What graphics card is "best" in 3D on Linux? got closed. I understand the "we can't do shopping recommendations" rule, but I think there's a case to be made that graphics hardware in Linux is a special situation.
First, it's not like the "should I get Canon or Nikon" thing we see over on Photo-SE, because, it turns out that the field is so narrow that there probably is a right answer at any given time.
Second, Linux graphics have always been a particular pain point. Having an exception here is not necessarily going to send us barreling down a slippery slope of hardware recommendations. Most other things I can think of can be made general in a way that'll be both good forever and lead pretty directly to the question-asker finding what they need at Newegg or wherever. ("What should I look for in a SATA SSD?", and even "How can I find if a wifi card is going to work?")
I've tried to ask the question in a very general way at How do I choose a graphics card for Linux?, and I hope that's valuable, but I'm not quite satisfied.
Might we have room for "What's the best graphics card for 3D in Linux in 2011?" type questions?
