The NVIDIA GeForce 6800 Ultra DDL or NVIDIA GeForce 6800 GT DDL graphics card is required to power the 2560 x 1600-pixel resolution of the 30-inch Apple Cinema HD Displays so if your machine is not fitted with either one of these, you will have to upgrade to something that is capable of handling the size.

The Dual 1.8 G5 came with NVIDIA GeForce FX 5200 Ultra with 64MB DDR SDRAM which was a option you could change at the store using the build to order function.
