The graphics cards are kept separate from the CPU and memory, in order to prevent heat escaping from one set of components to the other. In this case, HP has installed a pair of 1GB DDR4 ATI Radeon HD 2900 XT graphics cards in a dual-card Crossfire configuration. Bizarrely, these cards are installed atop an Asus Striker Extreme motherboard with an Nvidia Nforce 680i chipset. But the ATI and Nvidia products work together just fine, and they have the backing of an Ageia PhysX card.
