A lack of saliva can even make it harder for you to digest food or talk. To treat dry mouth, your doctor may ask you to stop taking any medicines that are causing it. The doctor may also recommend medicines that stimulate saliva production.
Erik Fair, Software Engineer, Investor, skier. A Graphics Processing Unit (GPU) is a special purpose processor, optimized for calculations commonly (and repeatedly) required for Computer Graphics, particularly SIMD operations.
One GPU renders one frame, and the second renders the next. This potentially allows 200% of the performance of having a single GPU in your system, because you have two GPU's rendering the frames to be output to your monitor. That being said, you always want to go for the more powerful single card VS a CrossFire solution if you can.
