Need a Good Graphics Card... Or Two

So I have been building my own computer and I have all the parts and everything put together, except the graphics card. I was going to get two GeForce GTX 680 video cards ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... ). However, they are still out of stock everywhere and are quite pricey. I was looking for a card that could replace it. My requirements are that it supports a lot of video games, I play games like WoW, SW:TOR, Skyrim, Team Fortress 2, and things of that nature. Also, I am going for a ridiculous set up with 6 monitors, all VGA hookups (5 Dell Monitors and 1 43" TV), so I need the card(s) to be able to support that and hopefully be a bit cheaper. I really appreciate the help, if you know of any that could do this or have any advice please let me know.
