MN has the least amount of ringing of any of the "cheap" scaling algorithms while retaining reasonably good sharpness. (SC has almost no ringing, but is very soft, and soft scaling tends to desaturate chroma)
Bicubic 75 is the closest thing to the more demanding scaling algorithms like Lanczos or Jinc, but does introduce some ringing compared to MN or SC. (though it's generally not an issue)

I just found madshi's comment on your comparison images:
--- Quote ---So I guess I agree with you to use either Mitchell-Netravali or Bicubic75 for chroma for good quality sources, when anti-ringing is disabled (SoftCubic for bad sources, though). It's probably a matter of taste which one to choose. Mitchell-Netravali has less ringing. Bicubic75 is sharper and has less aliasing, but has more ringing. Performance is the same.

So, is there any significant performance difference between Bicubic 50 and Bicubic 100, or is it just a sharpness difference ?

75 is the best balance between sharpness, ringing, and most comparable to the more demanding algorithms. (e.g. Lanczos 3, Jinc 3 AR etc.)
Performance requirements are the same for everything between DXVA and Lanczos on the list.
For what it's worth, I don't agree with Madshi, and I would basically never recommend SoftCubic for chroma scaling.
So far I have only found one video where SoftCubic actually looked better than other algorithms, and it was basically the video at fault. (extremely badly encoded) I would not set it globally.

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

Yes my gaming rig is watercooled.whatercooling for htpc doesn't cut it for me. Closed circuits are only available with 12 cm fans and for "smaller" components you will have noise from the pump. Thus you still use big cases.
Quietest htpc for me so far is aircooled with a very configurable fan controller such as the aquaero from aquacomputer and very carefully selected silent fans

The 'problem' with GPU reviews is the lesser models get panned because they're rubbish at gaming.
I've yet to come across a GPU review that is reviewed for 100% HTPC use only.

Well in the case of that one card, I read the Newegg customer reviews only for the words "fan" or "noise" and there were severall people who thought it was noisy. YMMV.
