http://www.avsforum.com/forum/26-home-theater-computers/940972-guide-building-htpc-workstation-server-643.htmlBy the way I have an MSI Z87M Gaming, i7-4770T, 8GB Memory - Corsair CML8GX3M2A1600C9,Case: Fractal Design Node 605 with:
MSI 750 TI TF Gaming (HTPC)
MSI R9 270X ITX Gaming (Office PC – was planned the other way round)
I have mostly all type of films and video with many of it interlaced.
I run the 750 TI with Chroma Up-scaling: Jinc 3 taps+ AR, Image Up-scaling: Jinc 3 taps +AR and Image Downscaling: CR+AR+LL.
The R9 270X is capable to run Image Doubling with 16 or either 32 Neurons and Error Diffusion (I have not tested it with all type of film and video material I have)
The 750 TI is practically inaudible, so I use it in my HTPC. The R9270 X ITX you can hear from 3m dsitance, so I placed it in my office PC.
Advantage of Nvidia is, that if you enable hardware transcoding support in JRiver, the 750TI will do the encoding/transcoding, leading to always <=10% CPU utilization regardless of the type of film or video material playing. This is not the case with the R9270 x putting sometimes up to 30% workload on my i7. NVIDIA has problems (much more GPU and CPU Workload required) with functions requiring Open CL support like error diffusion.
I also though about the A10 APU but from my experience now- if you are not into gaming - even an i3 with 35W TDP + 750TI can do the job which much more GPU power compared to the A10 APU but with a higher price.
