CUDA is now running on my system. The hard part is
prying the workunits out of Berkeley. I haven't tried
running GPU and CPU workunits at the same time.

Some statistics:
2 Pre-cuda Astropulse units:
159:26
159.55
they processed simultaneously on a dual-core
for about seven days.

3 CUDA units:
#1: 2:27:01
#2: 0:47:16
#3: 2:46
not including the time waiting for Berkeley 
to have workunits available.

A pleasant side-effect...
I use this computer for three non-Seti functions:
recording HD video, running VMware workstation,
and playing HD video. I only use the Nvidia card 
for playing HD video, otherwise I use the built-in
ATI graphics adapter with a smaller monitor. It 
happens that the ArcSoft video capture program
locks up if I start it with the CPU Seti running, 
I have to suspend it first. Video capture co-exists 
very well with the GPU Seti, however. 

A slight inconvenience...
I don't have any tools like Process Explorer to 
monitor GPU activity.

A link on physical memory limits for various Windows:

and something interesting at:

I was told that XP32 could not use more than 3GB, 
and I heard elswhere that 4GB slows it down.

The above articles do not seem to support that.

The main issue with XP64 is I have had trouble
getting anti virus that supports it. I had to pay
an arm and leg for V7 of CA eTrust.

Thanks for the help with CUDA.
