What are some good PCIE Nvidia cards? What brand is the best, or has higher quality? Is having two monitors worth it? Is SLI worth it, can I use SLI with 2 monitors? If I do decide to hook up 2 monitors can I use two different sizes? (IE. one CRT and one LCD) Ive always wanted to hook up my HD TV to my computer, is there a video card that will do it?
