Is it possible to have two TT 3200 in the same system? + motor query

None, at the moment

Good evening friends.

I am on the verge of building an HTPC and would like to know if it's possible to have two TechnoTrend 3200 cards on the same system? I read that I need a very powerful PC to be able to see two HD channels at the same time. How powerful ... is an Intel E6300 enough? :confused

Also, I would like to plug a motorized dish to this HTPC setup but a friend told me to use a decoder to turn the dish rather than the 3200 as doing so may fry the card. Again, is this true?

Thank you in advance.
