Hey guys, I need a good program for making a large directed graph, i.e. like 25-30 nodes with nice arrows. Would Mathematica or Maple work?

I want to get some math software, something that does everything. :) (or as close to that as practical) Of course I want it to be really easy to use. :) Yes, I realize that all of the above is impossible. I guess the best question is, which is most popular among, say, physics grad...

Is there a benchmark software available that measures your computers speed in FLOPS?
