It's been an age long battle in the PC gaming world.  ATI vs. NVidia.  Not since the early days of 3DFX and the birth of the 3D acclerator card has there been two steadfast competitors for consumer hardware dollars.  Sadly that battle is about to change again, after AMD's purchase of ATI in 2006, many wondered what would happen to the graphics maker.  Since that time ATI has managed to snag over 50% of the discrete graphics market share with it's 5000 series of cards, mostly due to NVidia's rough showing of its FERMI series of processors.
