I'm looking at building an HTPC and I wan't to know what parts of the system are taxed the most. For instance, would it be worthwhile spending the extra cash on a dual core processor, or would something as slow (and cheap) as a Celeron D at 2.5 GHz, be plenty of chip? Will DDR2 make a large difference? Should I be looking a single large SATA drive, or will IDE or even an IDE RAID work just as well. I'm trying to put together a good system for not a lot of money, so I'm trying to optimize the system and not have a lot of extraneous power I won't end up needing. It's going to run dual tuners with hardware encoding and I want it to be able to time shift and record simultaneously (or dual record), or dual time shift. The other question I have concerns tuner cards. Right now I have digial cable and would like to keep it. Do I just need to buy a digital tuner card, or do I need something else from the cable company to make it work. I'm not running high def, and I don't use the premium channels all that much, so i guess I could live with analog, although I would miss the music channels.
