Decoding should more or less just work. As well as 3D acceleration (which is 
surprisingly BETTER THAN ANY OTHER GPU ON LINUX, including the highest-end 
AMD discrete cards). I've been using i5-2400 (avoid the K!) since around 
January 18th.

I started with a Gigabyte board, but found out that its VT-d support was 
broken. Thanks to the well-publicised SATA glitch, I was able to get a full 
refund on it and switch to Intel DQ67SW. Much to my surprise, not only did
VT-d work fine, but it even worked flawlessly passing through my Radeon 5850 
to a KVM (for Bitcoin mining). I had been told by many various KVM 
developers over the last few months that graphics passthrough wouldn't work, 
so this kindof took everyone by surprise... as far as I know, I am the only 
one to have ever succeeded at this (with KVM; Xen has had some beta-level 
support for a while).

Note that 2.6.28+ does NOT work on the Gigabyte (but 2.6.27 does).
I reported a bug, but it seems nobody else with a Gigabyte has bothered to 
adopt it since I returned mine.
