I have an Asus cm5571 that I have installed an Avermedia video capture card into. Sorry my post count won't allow me to post a link. I'm generally well pleased with the video quality (1080i) but is a little choppy. I understand a video card upgrade will help this but I have no idea what I need. This pc won't be used for gaming just recording from the Comcast cable box and maybe old camcorder videotapes. Don't want an overkill video card but enough to do the job. I understand I may also need a power supply upgrade as well to handle the card. I'm a relative noob at computers so keep that in mind, thanks for any help.
