My PPD has been fluctuating a bit since this thread started:
- I initially was folding on my desktop using the Linux amd64 SMP client: ~1000 ppd.
- I got a dumpster dive PIII Celeron for an HTPC and started folding on that as well: still ~1000 ppd (the Celery averaged about 30-50 ppd)
- A buddy gave me his old ASUS A7N8X-E with an XP 3200+ inside, which made a lot better HTPC than the Celery. The Celery unit got repurposed to a file server and still folded: ~1250 ppd
- The A7N8X-E ate through its second PSU before I realized that the board draws all of the CPU juice off of +5V and I needed a PSU that can provide ~200 W on the +5V rail to run it flat out. I nixed folding on it to preserve my dwindling supply of crappy old pre-ATX12V PSUs: ~1000 ppd
- The Celery went belly-up and I picked up an old server with two 3.2 GHz Gallatin Xeons from eBay: ~1500 ppd
- I pulled my old broken laptop with a C2D U7500 (really, just a bare board at this point as the chassis has a short and the monitor is dead) out of storage to do video work. I started folding on it as well: ~2100 ppd
- The FAH program starts playing badly with my Xeon machine and hard-locking it, so I quit folding on it. New SMP clients also lower my PPD: ~1500 ppd
- The Radeon x1900 in my desktop dies and I replace it with a GTS250 and fold using the WINE CUDA wrapper: PPD fluctuates wildly between about 2500 and 6000 depending on what WUs the GPU gets.
The one thing I learned that's sad is that one $80 GPU can produce as many PPD as four computers containing 5 CPUs with 7 cores between them

Not sure what's going on there as it's rock solid stable otherwise.
