Good point concerning dual, simultaneous HDMI+DVI display: I had to stop and consider this before going with the Gigabyte board. After some realistic pondering about use I still think it will OK because though I will use dual displays initially (main 58" plasma via HDMI, 16" LCD on coffee table at my chair via DVI), I really won't need them both on simultaneously. The idea is to use the main display for TV and movies, and the smaller display for music management or quick, lightweight web browsing.
In the near-term (Q1 2012 post CES), my plan is to replace the 16" LCD with a tablet using wifi as the secondary display.
Then there is the rouge element in the form of encrypted cable TV on my current HTPC (Intel i3/Asus H67 mobo). Though it always works without incident on the 58" plasma alone, WMC will sometimes block the TV image with a HDCP error when another display is connected. This is the case with my current displays (in spite of my 16" LCD being HDCP compliant) but TV was viewable on both displays when I swapped the 16" Westinghouse for a 21" Vizio TV. Go figure...
In short, when it comes to dual displays I've always obtained the most reliable results with the widest range of displays when only using one display at a time. Optimal?-No. Acceptable for day to day use-yes.
Based on my NE browsing, it looks like the least expensive Asrock mobo with HDMI + DVI is $90
plus shipping. If the Gigabyte mobo wasn't discounted as part of a combo deal with the A4-3400 APU I'd go with the Asrock board but $23 in savings is-well-$23, and given that I don't know if this will be a long-term solution or not (Ivy Bridge?), I think it makes more sense to go with a low-cost AMD solution for now.

First, you have spend more money to get two physical digital video connectors on an AMD MB than for an Intel MB.
In addition, at least some of the AMD MBs do NOT support two digital monitors active at the same time. For example, this Gigabyte MB specifically calls out (page 21):
Dual Display: DVI-D + HDMI Supported = No.
The GB manual at least calls this out: at least one another mfg's manual does NOT note this.http://www.avsforum.com/avs-vb/showt...ighlight=llano
The reason for this limitation is implied in the page 8 block diagram in the GB manual. The diagram shows a switch between the APU and the HDMI and DVI connector.
This is a minus for me, because I figure that VGA connectors will eventually fade from future monitors and I plan on still having a dual monitor use for this MB someplace in the house in, say, five years. I'm basing this on systems that we currently have in the house/
