Am i wasting my time or not. I recently bought a Gateway 820gm pc with an Ati x300 video card. to put it simply the display sucks when I send my satellite signal to my 42" plasma screen. (looks great when the sat box is connected directly to the plama)Is it possible to run the sat signal thru my computer and get an excellent display? How about hdtv quality via computer. I don't seem to be able to get any info as to a card that will run on a pci express bus and deliver hdtv quality. Is this task impossible or just difficult. Any help in this area would be appreciated.
