I would think so, given that I could handle 720p w/just an 1800. Here's some 
further data to follow up from that thread (will post in that thread too).

System:
Athlon XP 2600, AGP GeForce 4 MX, nVidia 1.0-7174 driver

1080i content, kernel deint filter:
cpu 90% utilized (70% mythfrontend, 20% X)

720p content:
cpu 65% utilized (50% mythfrontend, 15% X)

Check out the link I posted that shows my nvidia-settings-rc, all my myth 
settings (database settings table dump, so not exactly straight-forward to 
decipher, sorry), and my xorg.conf (just added). Maybe some key setting in 
there differs from your setup.
