GPU recommendation for ROHQ

You still need to do Chroma upscaling no matter what, as I understand it, so some horsepower is necessary even if you're playing DVDs or Blurays at their native definition. How much you need depends on what scaling algorithm you choose for Chroma.

Actually, it's often quieter to have two separate low noise fans than one fan which has to work harder - especially as you are splitting the heat between two separate parts rather than making one part (the CPU) run hotter.

Yes, but CPU performance and power consumption is quite a bit worse.
It may work out to be a better balance for ROHQ though.

Yes, chroma upscaling is required, though it's not too demanding, as it's always scaled 2x and Madshi has optimized for that.

I would not recommend that - most displays do not have very high quality scaling at all. (which is why you would want to do it on the HTPC)
madVR (ROHQ) is going to get a debanding feature in the next release which will considerably improve lower quality sources, but requires more GPU power.

Looking to build a new htpc and update to the newest J River and was hoping I wouldn't need to get a separate videocard since I want to keep the fans down to a single one on the cpu. I'd only be watching DVD and Bluray>mkv rips.

I ran the high setting on this image with HD4000 (i5 3570) and later on a Nvidia GT430. Both worked fine as long as you don't try to deinterlace anything. All progressive material plays fine with no framedrops.

DVD's are normally interlaced correct?

Normally yes - http://en.wikipedia.org/wiki/DVD-Video
