Oh I see.  So the ION is actually even better than it looks!

I have the Asus ION board with PCI here and testing it now (my main 
system melted a few days ago, hence been without a system since we last 
corresponded...).  I'm finding it a bit hit and miss though... If I can 
get VDPAU working everywhere then it should be adequate, but because 
it's also my backend I'm seeing stalls here and there when stuff happens 
and some glitches in playback.  Also the frontend is quite "sluggish" - 
eg entering the music or media screens takes quite a few seconds before 
the list appears (I believe our UI widgets still need to be populated 
before they can display? Seems to create quite some lag on slow systems 
where there is a lot of stuff in the list?).  The music visualisations 
are also quite stilted...

So I'm back on the hunt for a beefier system.  I was about to buy the 
Gigabyte, but now wondering if I need something beefier like a fanless 
gforce 240**...

Can you get flawless full quality 1080P playing with all formats on your 
box?  Did you ever measure full power draw on your machine - I'm 
wondering if I can get away with a Pico-PSU 150..? Can then get rid of 
all the fans, etc...
