I can recommend ASUS M2NVM HDMI.
http://www.asus.com/products.aspx?l1=3&l2=149&l3=626&l4=0&model=1944&modelmenu=2Have done a lot of testing and everything work out of the box except for sound over dhmi which I haven´t been able to test.
Can't get it working wih my panasonic plasma (50PX8). It´s probably a problem with my plasma screen.
The board have onbard DVI/HDMI with HDCP compatibility and have a couple of jumpers that you set to select DVI or HDMI output.
For audio over hdmi it use the azalia chip. Same as on several other asus motherboards.
It can handle 1080P. Did a few test yesterday and i seem to work fine.
There is only one minor issue that I have seen.
The card use nforce gigabit ethernet and you will see these "nv_nic_irq" messages is dmesg.
Though everything seem to work fine.
The messages can be supressed with the following module option.
options forcedeth max_interrupt_work=20
