I'm putting together a new desktop system and I'm going to try to make the switch to linux for my day to day machine. I'll start with ubuntu as it would appear to the the most 'stupid user' ready. I'm wondering if there would be any real linux reason to go with a certain kind of hardware? I'll be using steam and doing plenty of gaming (steam and prob wine) is there better OpenGL driver support in one flavor or another? AMD/ATI vs NVIDIA? AMD vs INTEL?
