My 8800GTX is currently crunching at a blistering 25000-24000 khashs with one cpu core pegged @ 50%. The hardware is the exact same as above where I posted my results from the mac OSX Cuda Client but, running windows 7 ultimate 64bit. My system is still usable (browsed the web with no noticeable difference) but, windows menus and other aero enabled windows are laggy. Not trying to be "that guy" but, I am a little un-trusting of a closed-source client that sends bitcoins to a random address without knowing what else is under the hood. Then again if it nets me coins and only cost 5 thats not bad as long as that is all it does. Anyone using it generate coins yet? Also how many coins would you want to opensource the client?

[EDIT]
Wanted to add a note here that I have been running the client for about 8 hrs now and it is stable no crashes. Seems that puddinpop did a good job with the code. I think I can live with the 10% tax for now once I see the coins start rolling in.
