I run 4 monitors from my 7950. When going above 2 you'll need to use a displayport adapter. The best ones of these are the ones that are listed as EyeFinity compatible and are usually DVI. You'll want this for one of your current monitors and then use a DVI to HDMI cable to your monitor. For your TV I would use the current HDMI connection directly from your card so you get sound as well. If you were to use the DP port to try to go to the TV you wouldnt get sound thru the tv, which i'm not sure if you want anyway.
