Suggestions on graphics card?

I've been wanted to build my my own gaming PC. I was looking for graphic cards but couldn't find anything in my price range. I was going to use the SAPPHIRE Radeon HD 7970 3GB OC, but it was sadly (At cheapest as what I could find.) $500. I need a graphics card that can run TF2, Minecraft at maximum settings, watch videos at 1080p, etc. In the future I'm most likely going to start playing the higher graphic games like Battfield 4, etc. Any suggestions. It would be awesome if I could get many different suggestions in case one isn't one I'd need. In advance, thank you!
