I'm running a 3.4 GHz P4 with Hyperthreading turned on, and I can crunch 2 SHA-1 WUs every 30 minutes - they run rather smoothly, only take 6-10 MB of memory each, and are worth 10 pernts each, regardless of the pernts claimed on upload (most of my claims are for 3-4, so it goes rather quickly). In addition, these projects only have a quorum of 1, so the results get validated very quickly on upload, mostly within 10-15 minutes, tops. No waiting days for someone with a slower computer to finish that last WU in your quorum of 3 to validate results... 
So if Crypto is where you want to throw some CPU power, SHA-1 would be a great choice! A dedicated 3GHz+ dual core Intel could probably be close to a 1000 ppd machine on this project...
