            Hey GeForce gamers, I am excited to introduce our new flagship dual-GPU graphics card.  With 1024 CUDA cores, 6 billion transistors, 3GB of GDDR5 memory, and over 2200 individual components all packed into an 11 inch dual slot PCB, GTX 590 is nothing short of an engineering marvel.  Designed to deliver not only the world’s fastest DirectX 11 performance, but also the world’s quietest acoustics for a dual chip graphics card, the GTX 590 offers 50% faster performance than GTX 580 while nearly matching its little brother’s award winning acoustics.
