A little off topic today as the world has gone all quiet. You can be an all-knowing computer science boffin and still not grasp the concept of the "GPU" and what it does. Pretty much everyone knows what the CPU is and does, but when it comes to graphics, a lot of us are left in the dark.
The Mythbusters duo teamed up with Nvidia to show a more interesting demonstration about how the CPU and the GPU related to each other, but also why they are two very separate entities in a computer.
If you want to see these in high-definition; the whole video and the slow motion replay, you can download them in 720p, 480p and 320p formats directly from the website. I just uploaded this to YouTube if you were short on time, as most of you probably are.
