I'm just wondering what the cheapest way to go about this is. Currently my graphics card is the 8800, but I think I've read that you don't have to have the same graphics card to add more monitors (the ATI base graphics card will do just fine). So do I just need to purchase one from apple or am I able to get one cheaper from anywhere else? Also all of the supported graphics cards output 1920X1080 right? And on a side not - this output will be going to my television - is there any way to make front row default to the television output?
