Can you recommend a powerful graphics card if I give you my specs?

Greetings,

I currently have an HP Pavilion Elite Desktop Computer with an AMD Phenom II X6 (2.7GHZ) processor, 6GB RAM, Radeon 5700 series graphics, and a 600W Corsair Power Supply. I want to spend 2-300 dollars to upgrade my graphics card. Do you have any recommendations and do you think my PC is compatible for modern day cards. I believe I have PCIe 2.0, but I don't know how to tell.

Thanks!!
