Vista is never likely to run as fast as XP since they have stuck another
layer of "Protection" in between the hardware and the drivers in order
to reduce the possibility of bad drivers crashing the enttire system.
The result is that more CPU time is required for processing and the
extra layer (Bloat) does nothing much to prevent bad drivers from
crashing the system but seems to make "Good" drivers harder to develop.
Instead of applying constructive criticism to these issues some MVPs
will simply tell you it's the hardware manufacturer's fault for
producing late / bad drivers - but will not address the question of how
a manufacturer is supposed to write quality drivers when the OS is not
"Finalized" and is still being cobbled together a week or two before
release. Note the many comments about the Beta and the RTM "Should" be
the same... which indicates that those making the comments are NOT using
the public released version
This is working here
http://www.nvidia.com/object/winvista_x64_158.18.html
but useless in SLI mode...
Card is 7950 - also BFG X 2 but of course unable to use the 2nd one.
You might see if you have the best chipset drivers and tell your brother
to make 100% sure he keeps a copy of the working driver set, new drivers
may fix one thing but break another.
Also, you must UNINSTALL Nvidia drivers completely before updating, you
should not install over the top. My experience is that sometimes over
the top works, often it does not.
Good luck
