Nope... I doubt any graphics chip is general-purpose enough to have a hardware "Rotate" instruction, so the client would not be fast for RC5 at all. In fact, I would be surprised if any graphics chip had an instruction set general-purpose enough to even run the RC5 algorithm at all. You need instructions like conditional branches, integer math, and loop counters to implement the RC5 algorithm.

I think a GeForce256 (www.nvidia.com) client would be *very* fast. But
better write a DirectX client :)
