As the release date gets closer, more info about Crysis has appeared.  We now know that the CPU will have a big impact on the overall performance of the game, and that the game will be able to utilize 4GB of RAM or more.  Keep your eyes peeled for more on this game as it develops.
Cervat Yerli, who seems to spend more time talking to the press than actually working on finishing the game, revealed that on most systems, Crysis is likely to be CPU bound. “If [your system is] balanced, we are more CPU bound then GPU, ” he told Shacknews. http://www.shacknews.com/featuredarticle.x?id=639 ” Multi-core will be beneficial in the experience, particularly in faster but also smoother framerates… We recommend quad core over higher clock.”
