My motherboard is actually a Gigabyte GA-E7AUM-DS2H, which I bought
this past April and don't see on Newegg any more.  The DFI doesn't
have firewire or eSATA, in case that's a concern.  For some reason,
the Intel/vNidia motherboards are far more expensive than the
AMD/nVidia motherboards.

For 1080i, I am actually stuck using the Bob deinterlacer because,
unless this has changed recently, it is the only deinterlacer that
reasonably handles the tendency of NBC (and maybe other networks) to
mix progressive and interlaced frames.  The "better" deinterlacers
give jumpy video.  I use Advanced 2x for SD, though.  Honestly, on my
1366x768 TV, I don't see much of a difference between the
deinterlacers on 1080i content.
