Do you know anything about water cooling. This company is selling a water cooled version of the R9 290 that is over-clocked. Seems like a quiet solution for 4k and madvr? http://www.visiontekproducts.com/index.php/component/virtuemart/graphics-cards/visiontek-cryovenom-liquidcooled-series-r9-290-detail?Itemid=0

Not familiar with that technology but sounds like an idea. For my theater room I built a 'stage' which sits below the screen. With easily removable covers it means all the electronics easily fit in there with lots of cooling fans to vent out the sides. Actually one side of the stage is the intake fans and the other side is the output side, so the air flows through the electronics from one end to the other. Each of the components then have their own one or more fans to blow air from the front to the back. With this concept the components keep very cool, it is quiet because the stage is covered in a thick black cloth material, and the panels remove easily from the top to make it easy to work on wiring and components. So far the video card runs about 32 degrees C so quite cool.

I'm in this boat now as well. I currently have a 5450 which out-of-the-box (as in driver defaults) is no good for ROST with BluRay's, and only works with ROHQ on low madVR settings.
So deciding between a 6450 and maybe a 630? Need low profile as my case is low profile only!

I just added the Asus passive-cooled Radeon 6450 in my low profile case, and I can now run ROHQ with DXVA2 image upscaling and downscaling, and SoftCubic chroma scaling, and nothing checked in the "trade quality for performance" list (except for subtitles, since I don't care much about subtitle quality). (The color using SoftCubic looks very good, and since that is what is being scaled, it seems fine to my eye.)
I use the madVR SmoothMotion feature since I watch a fair amount of 25fps content and my monitor does not have a 25 or 50fps refresh rate.
I have "hardware acceleration" unchecked, in order to allow the GPU to be used for madVR. I have a dual core 2.8ghz and software decoding using Hendrik' LAV decoder works fine on everything.
(I have all the buffer settings in madVR maximized, since the Asus card was way more memory quantity than is otherwise needed.)
I have not tried Nvidia for HT-PC so I cannot compare them. The Asus card is US$42 new, so it is not much of a gamble if you find it is not suitable.

Unfortunately, the 6450 or GT630 are not very high performance cards, but they do seem to be the fastest things you can get with a low profile passive cooler. I think the GT630 is the faster of the two, and personally I prefer Nvidia. I have a GT610 I picked up as a backup card (cheapest I could find with an HDMI output in a pinch) and it will run madVR on the lower quality settings without too much trouble.
The fastest "standard" low profile card I've seen is an AMD 7750, though it is not passively cooled. It should be quite a bit faster than the GT630 though.
There's actually a very strange looking low profile 7850 available, but I'm not sure how quiet that will be.

I would suggest using Mitchell-Netravali rather than SoftCubic for Chroma. SoftCubic has a tendency to desaturate colors. (actually, MN does as well, but to a much lesser degree)
I don't know how DXVA scaling is with AMD, but on Nvidia it's actually more demanding than the lower-end scaling options in madVR (ROHQ) and looks worse.
