I have an older system that I am thinking of turning into a HTPC but I believe the CPU is too slow. It is a 1.2 GHz AMD Athlon processor. I believe they can be overclocked but by how much I donlt know. I would need a video card for DVR and also have the ability to record HD OTA signals as well as display them. I guess the first ? is....should I even bother with such a slow system? What's the lowest CPU/RAM combo to look at for basic functioning. I don't really need the bells and whistles. Just basic DVR, HDTV for the future, and watching normal TV at the same time as recording. Well. Any help would be appreciated. Thanks.
