Power supply is an important consideration, and you raise a very important
point. Nearly every one of the 300 OEM Named partners of MSFT who sell
boxes sell the lowest end power supplies possible on high end machines
purposely to save money. The older the machine, the more likely you may
have to carefully replace the PSU making absolutely sure it is the correct
one for your machine. You can't even spec a better power supply for nearly
all of them when you order, because with most of the PC makers, the PSU is
proprietary and there aren't choices from the PC maker.
However, whichever Vid card that you decide on, the major card manufacturers
(unlike most tech support) have 24X7 tech support and it's excellent (if
only all other types of tech support matched their experience, enthusiasm,
and quality) and they can tell you/confirm exactly what the PSU requirements
for that card are if the information isn't included with the card. With a
number of cards, you won't brown out, the video card just won't run with
the inadequate PSU--but your warning is a very good one and it sure could
happen.
Also the factual minimum RAM for Aero Glass is not 128 MB RAM but in fact,
64MB RAM in reality.
Dale White did a really excellent job of posting several specific cards and
prices on this thread. Very nice specific examples.

Hi,
Minimum spec's include 128MB of memory, pixel shader 2.0, and Dx9 support
as
well as WDDM driver support from the manufacturer. The 9200 is not
sufficient for this. From ATI, the 9500 is the minimum card that will work.
Also, you need to have at least 1GB of system memory as well.
And don't forget Power supply. gs7600 starts at 350 watts. If you don't have
that minimum, you'll brown out for awhile until the PS explodes taking
everything with it.
