You think your home-built gaming PC is rocking with a dual-slot PCI-E graphics card wedged into your blinged-out case? You haven't seen anything yet. Asus just pulled the curtain off its newest piece of gaming indulgence, the Radeon HD 7970 DirectCU II TOP. It's the latest in the manufacturer's series of factory-overclocked cards, which include massive cooling systems designed to keep the GPU running at efficient combinations of speed, heat load and fan noise. This configuration has a new trick up its sleeve: a triple-slot configuration, where the combined circuit board and cooling unit take up the same amount of space as three normal-sized discrete cards.
