Upgrade 2009 27" iMac's Graphics Card?

Hello All

I have read many confusing posts about upgrading graphics cards in iMacs but I haven't been able to find a definitive answer yet as to whether i can do this.

I have a Late 2009 27-inch iMac (model iMac10,1) with ATI Radeon HD 4670 256mb graphics.

I just need to know if it is possible before I buy a card and begin the tedious process of taking the computer apart, and which cards will work and are available for purchase.
