I'm doubtful to be honest. Crytek will need to seriously overhaul how the game is produced to still be able to look as good and run better on lower end systems. Big performance gains from game engines like those don't come easy. Even the HD4870X2 can only max the game smoothly at 1920x1200, let alone 2560x1600, and that's without AA too. Meanwhile other similarly good looking games like Episode Two and Call of Duty 4 are rocking nearly three figure frame rates at 2560x1600, and with AA on the same hardware. The game's a vast system hog.
