I think cost effectiveness is what I am after. And I don't think I have room for two PC's, external hard drive, my receiver, sub, PS2, PS3 (which I finally bought last night and played with until 3:30 this morning) in my entertaiment center, and I would rather not have to buy 2 cases, motherboards, power supplies, keyboards... yada yada yada. With the 2 graphics cards, I think I would abandon the clone screen option and instead use the monitor for tracking downloads while the movie is playing on the TV. I may use torrents or have to render a building or buggy while I am watching a 3D movie and would like to keep the progress in my peripheral - I think more opps would also present themselves after having the setup in place.
