Update:
StarCraft 2 Graphics Requirements Confirmed - Contents of this analytical article was later confirmed by documentation from Blizzard/AMD.
Recently I was asked about the demands and requirements StarCraft II would place upon a user’s computer system. The first section I have put together is a simple system that will most likely boot and operate the game to a basic degree. Underneath I have also gone into more formal analysis of some of the specifications and demands we know StarCraft II to have from what Blizzard has released so far, and what is in that section is designed to be said with certainty. Something like this, or better should be used to play StarCraft 2.
