Finally GPUGrid seems to work on Windows. My venerable 8600 takes 45 hrs to do a WU worth 1980ish credits. The rather newer 9600 takes 20 hours. The way it works is the GPU acts as a coproccessor to one of the CPU cores. This makes it an ideal upgrade route for the slower PCs but it wouldn't make much sense for say the ubercruncher where a single core doing optimised SETI can easily outcrunch the 8600 and is almost on a par with the 9600.
I got stomped yesterday by Buster who replaced me as team credit-leader. Cool!
For all you figure fiends here are more numbers for Milkyway & CPDN, each based on just 4 work units, running on the ubercruncher.
Project ______ 6WUTime ________ 6WUCredit _______ Credit/Day
Rosetta _______ 11.1hrs ___________ 286 _____________ 2474
WCG _________ 20.4hrs __________ 399 _____________ 1877
Einstein ______ 43.8hrs __________ 1425 _____________ 3123
Cosmology ____ 3.22hrs ____ ______ 300 _____________ 8944
Seti__________ 12.2hrs ___ _______ 374 _____________ 2951
Seti[optimised] _ 5.9hrs ___________ 431 _____________ 7013
Yoyo _________ 42.3hrs __________ 1692 ____________ 3840
CPDN .................. 879hrs ....................... 26749 ........................ 2920
Milkyway .......... 13.6hrs ....................... 784 ............................ 5534
BTW Cosmology has since altered its credit structure since the above and is now much less rewarding!

So are you going to update the numbers for csomology? How long before you think you can put a decent estimate of GPUGrid?
Mmm, I'd have to run some cosmology to see just how slow it is. Maybe later.
I'm just about to post about GPU.
