When I read threads like this, it becomes clear why publishers demand that developers put 'Supports DirectX10', 'best performance with Quad Core' etc. on the box. Of course its the sponsoring hardware vendors who make them put 'best textures with 64bit AMD' or similar on the box
Hey just play the game and enjoy it. The reason I plan to get Quad core soon is so I can record TV and download files with one core, run the OS and sound and graphics drivers on the next, while playing Crysis on the remaining two. Maybe the sweet spot in 5 years time will be 64 cores?
