So true....but I am doubtful about my graphics card... This is what fifa 12 requires.... Snow Leopard (and up), an Intel Core 2 Duo processor, 4GB of RAM, and ATI HD2600 or NVIDIA GeForce 9400M or greater with 256 MB of Video RAM. The download comes in at just under 7GB in size.

My graphics card is amd will it work?

Or greater. You have more than enough graphics card.

Can't help you there.

Thomas, you know all the specs of your Mac, what does Fifa12 require?

My guess is that all will go fine. Do you know that you can download the game here?
