Evaluating video cards for dual-monitor 43" plasma
I'm building a HTPC utilizing dual-monitor 720p 43" plasma TVs. Virtually all benchmarks and specs are relative to 1080p. What is the relationship between 1080p specs and my video processing needs? Or put another way, how do I understand the power of a video card relative to 720p? I'll gladly welcome any input about my project, especially if you have experience with a dual-monitor HTPC. I'm building this PC ground up but I do already have the TVs. Thanks

are you planning on doing any gaming/editing? what is your budget?
Virtually any modern graphics card is going to be able to manage 1080P. Look for graphics card with HDMI 1.4 output.
I won't be doing any editing. My budget is the $300 range. I might decide to get card nice enough to game with. I like what I have learned about and the price of the GTX 770 or the R9 280X cards. But I have been evaluating them based on resolutions higher than my tvs can achieve. I would buy one of them if it isn't over kill for 720p. As an example, would a slower card, R7 265 say, perform similarly on a 720p monitor as a faster card, R9 280x say, would perform on a 1080p or higher monitor?
The resolution of the video output is going to be 1080P or better on most graphics cards. The R7-265 is adequate for most purposes.
For dual monitors a 4Gb ram card will perform better than a standard 2Gb card. Personally I'd go with either the 770 or a 280 or 280x for the simple reason that at 720p you are going to want to set as high a detail setting as possible. While a 265 will work just fine, a more powerful card will not be under as much stress, and will run cooler and quieter for the most part.

The 1080P resolution is the next step up in resolution from 720P.
