OK, the 128 MB version it is then. As for the heat - I have added a
pair of 70mm fans behind the CPU heat sink and snipped off excess metal
in the grill behind the fans. That alone has dropped my CPU temps about
7C. One fan overhangs the top of the CPU heat sink and draws air past
the RAM. It should help clear air from around the video card too.

I've used both and they perform for the most part identically, both in
Windows and on the Mac. The 9800 core wasn't really powerful enough
yet to make use of the extra 128M of VRAM. Save your money and get
the 128M version. Truth be told, on any machine you're going to be
using a 9800 card in, the machine itself will be more CPU bound than
graphics bound anyway. Other than the last generation of PCIe G5
towers, I'm not aware of any G series machines that can even use
uncompressed textures without choking anyway, I certainly know my dual
2.0 Ghz G5 can't. VRAM determines how big of "textures" the card can
process and display. Translation: Eye candy. The VRAM has nothing
to do with how fast the card is, except in newer generation cards that
natively handle uncompressed textures and other higher end features.
The 9800 isn't one of them. :-)
Pretty much my experience too on a MDD.
The 256mb version seems to run quite a bit hotter as well so if like
me you install it into a MDD then look to add some additional cooling
unless you want some cooked internal components.
