I have a Mac Pro that I bought Jan 2008 with an NVidia GeForce 8800GT Graphics Card. I've tried to figure out if I could purchase a new Apple 27" LED to work with my mac. Does anyone know if there is an adapter for use with the LED screen as I don't have an Apple Display port on the graphics card or would I have to buy a new graphics card for the LED to work. Thanks in advance any help or advice appreciated. I have tried to look online and figure out whats best but I'm stuck.
