In the two horse race of performance video cards, things have been pretty cyclical. One company would release a new whiz-bang card, then the other company would release their response. This was followed by a similar cycle of tweaked versions of the same cards. In the last two release cycles those tweaks came in the form of dual GPU cards, which sandwiched two cards into one package. The most recent cycle left off with ATI releasing their dual GPU solution in the form of the Radeon HD 4870 X2, and NVIDIA responding with…nothing. NVIDIA finally turned their nothing into something by releasing both a dual GPU solution and a tweaked single GPU card, and they are bringing vendors like ZOTAC along for the ride.
