Hi... we're getting a new Mac Pro to run our CAT V4.

In the configuration options at the mac store, they have various options for the graphics card. the standard Nvidia GeForce 7300GT, an ATI Radeon X1900 XT and a Nvidia Quadro FX 4500.

The Nvidia Quadro FX is way too expensive, but we were thinking of getting the ATI Radeon X1900....

Is is worth the extra $250 in terms of performance for Cat V4???
