The opening day of PAX East in Boston was capped by a fairly humongous presentation from PC gaming hardware manufacturer Nvidia, representatives from which introduced two new graphic cards: The XLR8 GeForce GTX 480 1536MB and XLR8 GeForce GTX 470 1280MB. The new pieces of hardware are priced at $500 and $350, respectively, and have a tentative release window of mid-April.

In addition to being capable of rendering some impressive visuals -- as seen in the presentation's 3D, multi-monitor demos of Battlefield: Bad Company 2 and Metro 2033 -- the two devices come loaded with some neat bonuses. Among these are a handful of download vouchers for high-def films from Sony Pictures and two tech demos titled Design Garage and Supersonic Sled. We really, really hope the latter can be fleshed out into a full-length game.
