MSI is "pushing the limits" with trying to come up with super-dooper model names for its top-end factory-overclocked graphics cards. Until now, the "Lightning" model name has come to be known as MSI's highest factory-overclocked. MSI has a Lightning edition of its NVIDIA GeForce GTX 580 graphics card carrying 832/1664/4200 MHz clock speeds (core/shader/mem effective), but now feels that the Twin Frozr III and the VRM can push it further up. Enter the MSI N580GTX Lightning Xtreme Edition. The new card is said to push the out-of-the-box clock speeds further up. To look at, the Xtreme Edition doesn't look much different, other than the blue fans and black shroud. The company is also working on a highly-overclocked GeForce GTX 560 (non-Ti) graphics card with a dual-fan cooler.
