- I'm surprised to hear so many people say "do quads"...that would increase bus traffic by 4x...

Not if you are using VBOs for vertices and texcoords - and your vertices are fairly static. If your vertices are changing via CPU per frame, then you're correct; if the vertices are changing via vertex or geometry shader, it's less of an issue.

quads/quadstrips are the best way to avoid tile/edge artifacts. If that's not an issue, then point sprites are fine.
