With CPU-integrated graphics upping their game and handling most casual gaming and HD video watching tasks without too many problems, AMD and Nvidia could find the bottom dropping out of the low-end discrete graphics market before long. The question is, how do the companies make up for it? One answer lies on the opposite end of the spectrum: high-end super-duper-computers often take advantage of the raw computational power of GPUs. That same processing efficiency is opening up new (final) frontiers -- Nvidia's helping a Lunar X team in their quest to go to the moon, Alice!

Gaming laptops have made big strides in recent years, but let's be honest: getting great frame rates on a mobile device is easier said than done. A pair of new products unveiled over the last couple of days hold the promise of powerful portable performance, however. First up is the GTX 680's little brother, the Kepler-based 600M class mobile GPUs, which are smaller, faster and less power-hungry than their predecessors. Meanwhile, the thermal gurus over at Asetek have introduced a new slim form factor liquid cooling technology designed just for notebooks and AIOs -- then overclocked a Alienware M18x to 4.4 GHz to show off its chops.

While the new Radeon 7000 video cards seem to be launching and garnering headlines on an almost daily basis, it would be foolish to forget that AMD is far from the only 800 lb. gorilla in the discrete graphics room. As regular reader JohnP regularly reminds us, several signs point to Nvidia releasing the Kepler-based GeForce GTX 680 on March 22nd. That's just a couple of days away, so we thought we'd do a quick round-up of the various GTX 680 rumors floating around the web.
