"better at" carries little meaning in this context. If you want to do 
both OGR-25 and RC5-72, you're better off running OGR on an Athlon, and 
RC5 on a G5. Until you say "this many keys is worth this many nodes", 
you can't compare speeds between the projects.

And really, OGR-25 is a lot more feasible than RC5-72, if you say 
"completing OGR is worth as much as completing RC5". And I don't really 
see the worth of completing RC5.
