Things might be looking bad for Nvidia at the moment, what with a massive stock decline, less than expected revenues and defective hardware to deal with, but the opposite is true for AMD. The Radeon HD 4800 series is being well-received so far, and AMD has plans to offer even more of the cards very soon. The Radeon HD 4870 X2, a dual-GPU monster aimed at the hardcore gamer and enthusiast crowd, is supposed to be here before the end of this month.
The high-end (and high-priced, at around $499) card should sport up to 2GB of GDDR5 memory, an impressive amount by anyone's estimates, and judging by the performance stats of the other 4800 series cards will be a great performer.
