It looks like NVIDIA’s dual-chip GeForce GTX 590 has been pushed out by at least a few weeks. Video card makers said the February timing has been pushed back to mid-March “at the earliest”, but now it’s not clear from some Internet rumors what would have triggered the short but noticeable delay. AMD would ship its own equivalent, the Radeon HD 6990, about a month afterwards.
Both are designed around the basic equivalent of combining two of a given company’s second-fastest graphics chips on a single card and using either CrossFire (for AMD) or SLI (for NVIDIA) to unite them together. The performance is both the fastest from a single card and lets those with very high-end gaming setups fit the equivalents of four or even six cards (in theory) in one system.
