I'm building a home-theater PC and I have a question about how much processing power do I need.
I have an existing home-built desk-top system with a dual core AMD Athlon 3Mhz that has a TV-tuner and video PCI -cards. I use the Linux-based Myth-TV software to receive over-the-air digital TV, watch live TV and make the occasional recording. In the new system, I just want to receive the digital signal, make the recording, store it and access it over my home network as needed. My home-desktop PC would actually be the front-end where I would watch recorded programs. There is no connection to a TV set now.
The first option would be a Micro-ITX system that uses a Intel Atom series processor such as the Intel Atom 330 and on-board Video, 1.6 Mhz with 2.5 inch hardrives, and no DVD player or an AMD E-350 APU 1.6 Mhz also with on-board video.
The second option has more processing power and consumes more power. The second may be a larger case, maybe a Micro-ATX size with an Intel i3 processor such as Core i3-2100 at 3.1 Mhz or an AMD, A series like the Llano A4-3400 at 2.7 Mhz. I think these are about 65 Watts.
I'd prefer to go with the system that consumes the least power, so I'd prefer option 1. But does the process of using ota digital signals by the TV-card need the extra processing power of option 2? Would the process work at the lower power at all? Perhaps going with the bigger processor will ensure the signal will be processed normally? Your views will help make a good decision about this new project! Thanks in advance!
