Valve has unveiled a 64-bit version of Half-Life 2, which is intended to be played on AMD Athlon 64 FX processor-based systems. The company believes that combining the performance of AMD64 processors with the 64-bit version of Valve's technology results in advanced and powerful games.

"Bringing the Source technology to the AMD64 processor platform is an important step in the evolution of our game content and tools," said Gabe Newell, Valve's co-founder and president. "This investment in future processing will allow us, and third party developers working with Source, to push the boundaries of the gaming experience."
