I've been looking too, but you have to remember a lot of other factors influence RAC - little things like how much time each day the system is actually crunching, etc. Go into the details of those top computers to look at the turn around times and fpu & integer Boincmips, etc to see which cpu is actually going to be doing what you expect.
Then you have the problem that some projects greatly favor one cpu over another ... decisions, decisions.
Right now I just looking for something fairly inexpensive to replace the old slot 1 P3s I have (and thin out the crowd some). A couple of mid-range C2Ds and maybe a AthlonX2 will give me a fair amount more crunch and significantly more room ...
One new box a month is my current goal - money allowing.
