GPU recommendation for ROHQ
BrandonT:
I'm just getting my feet wet with what ROHQ is doing, but my intent would be to run at or near the highest level processing. SD DVD>1080P scaling. I assume native 1080P in the bluray mkv's will not be a problem. No desire for 4k at the moment.

My understanding is that Chroma upscaling still needs to happen even with Blurays as the Chroma information is stored at 1/4 size.
The scaling algorithm used can make a big difference in what kind of video card is required. If you want to use the highest quality scaling algorithms (i.e. Jinc), there is no integrated graphics solution that I'm aware of that will work.
It might be worth testing your new rig with the integrated graphics first and see if you like what you can get out of it or not. Some of the "lower quality" scaling algorithms still look pretty darn good.
Also, you might want to have a look at this thread: http://www.avsforum.com/t/1477339/so-youve-built-your-htpc-now-what-is-next-how-to-get-the-ultimate-picture-and-sound-quality-from-your-htpc-madvr-svp-xbmc-mediabrowser-jriver/60#post_23512510
It shows that the HD 4600 integrated graphics can run some pretty good settings (but not the best settings) for film, but has a much harder time with video, which is to be expected.
rec head:
I'm running an i3 with HD3000 and ROHQ at it's base settings. It runs BD and DVD MKVs just fine. Everything looks really good. I have started playing around with higher settings but video gets choppy. DVD upscaling is where I would like better performance but I don't know if it is worth a new video card.

Thing is, the decision for what brand cpu to go with in the first place kind of hinges on knowing if it can satisfy my needs. If Kaveri (or Richland) can do it, then I'm leaning towards that. But if they can't I'd probably go with Haswell and a AMD card.

And just so I understand, all this really only needed if I upscale DVD? If I just want to play DVD as is (standard def), and bluray as is (HD), than it any chip should be fine? Or are there other video processing that ROHQ must do that would require a lot GPU horsepower?
