Computer maker WidowPC hopes to tap into the 7.5m and growing population of online roll-playing game World of Warcraft by building a PC it claims is designed specifically for the game.

The company says the WoW Online Gaming PC, which is being launched in the US, features "a new form of intelligent networking technology" that reduces the amount of lag people experience when playing the game.

The boost in performance is achieved using Bigfoot Networks’ Killer network interface card, which is designed to ensure fast online gaming.

"Most of our engineering staff are World of Warcraft players and have been designing PCs for their friends," said WidowPC chief executive Joshua McClure. "Our customers said we should offer an affordable machine that plays World of Warcraft exceptionally well.

The product is available for $1,495 (£780) in the US.
