Modern supercomputers are essentially clusters of hundreds of processors linked by fast networking. The speed of these processors is comparable to (and often slower than) those found in PCs! Thus, if an algorithm (like ours) does not need the fast networking, it will run just as fast on a supercluster as a supercomputer. However, our application needs not the hundreds of processors found in modern supercomputers, but hundreds of thousands of processors. Hence, the calculations performed on Folding@Home would not be possible by any other means! Moreover, even if we were given exclusive access to all of the supercomputers in the world, we would still have fewer cycles than we do with the Folding@Home cluster! This is possible since PC processors are now very fast and there are hundreds of millions of PCs sitting idle in the world.

that means y not use 1 super computer instead of giving it to us. Not that if every1 used a supercomputer it woudl suck. If u have the same amount of super computers vs. normal somputers the super computers will wipe the floor. SO therfore back to my question can any1 else find a better folding machine?

You have to understand, you'd have to setup and run a separate folding client for each processor. In intel HT systems, you have to run two clients to take full advantage. So the more processors you add, the more clients you have to run. And it's not completely additive. A dual processor box isn't going to be as fast as two discrete boxes.
That said, if you were willing to compile Folding@Home for EPIC (Itanium2), that would be your best bet. Are you asking for a single workstation? A dual Opteron box would probably be the best of the easily accessable setups. But if you want all out performance, I'd say Itanium2 (if you compiled the code correctly for it, not running it in x86 emulation).
Unfortunately, you can't compile it for anything else. They don't have it set for anything other than x86. So no MIPS (SGI, etc), SPARC (SUN, Fujitsu), PA-RISC (HP), or Itanium. Meaning an 8 way Opteron server configuration with 8 clients would be the best single box you could get for folding@home.

Reason: Realized F@H is only available for x86 and isn't open source

No. DMOS's 8 way opteron is the only thing available.
Folding is designed for parallel processing (several computations at the same time). Supercomputers are designed for fast serial processing (several computations in a row).
That's why a Folding process is tied to a single processor. If you could trick Folding into thinking a 1024-way grid computer was a single processor, that would wipe the floor with an 8 way opteron.
