Nearly half a year after the initial projected release date, Nvidia premiered its new GeForce 400 series of cards at PAX today. After a development period mired in controversy, Nvidia showed off the capabilities of the 400 series in a 3D presentation demoing gameplay footage from titles such as Battlefield: Bad Company 2 and World of Warcraft. Despite the polished presentation, critical reception has proved to be tepid at best. A number of sites have criticized the line's mediocre performance in benchmarks compared to rival ATI's line of Radeon cards, with some older cards even surpassing the new line in gameplay performance; some also cite the cards' extremely large power draw as another point of contention.
