There's no official word about this laptop, and if any of you are caught or killed, the secretary will disavow any knowledge. Still, you can't stop a good rumor, which is why details have emerged about a supercharged edition of MSI's GT780DX that dials the original hardware up to 11. The GTI 780GX has a 17.3-inch 1600 x 900 display (with the option to boost it to 1920 x 1080) and weighs a workout-worthy 3.85kg. Justifying that heft is a Core i7 Extreme Edition 2920XM CPU which'll hit 4.16GHz in Turbo mode, thanks to a "Cooler Boost" heat-sink that'll stop the laptop from singeing your flares. Paired up with such a meaty chip is 16GB of DDR3 RAM, a GeForce GTX570M (itself with 3GB of DDR5 inside) and space for two (two!) HDDs that each hold up to 750GB. You'll also get a Steelseries gaming keyboard, THX Sound and a 9-cell battery. Given that the laptop doesn't officially exist yet, there's no word on pricing or availability but we'll keep our eyes peeled.

While the jury might still be out on whether you can have a thin-and-light coupled with gaming prowess, over at MSI, it's pretty much business as usual. It's that kind of mantra that's produced the GT683DXR that lays before you, a rehash of the existing GT680 but with gussied-up internals, spearheaded by NVIDIA's GTX 570M. In our brief overview several weeks ago, we were impressed with its performance, but dismayed with its flimsy keyboard, possessed trackpad and general girthiness. So, were we completely off the mark? Or did our impressions change after spending a little more time coddled by its side? Join us in finding out, after the break.

We might still be smitten with a certain svelte ebony beaut, but we're aware some of you require absolute maximum performance from your "portable" gaming rig. Here to heed your call for blistering frame rates is MSI, which has gone and refreshed two laptops from its gaming lineup: the 15.6-inch GT683DXR and its big brother, the 17.3-inch GT730DXR. While both retain the Core i7-2630QM from their forebears, the duo now feature NVIDIA's beefy GTX 570M with 1.5GB GDDR5. And just like their predecessors, either can be stuffed with up to 16GB of RAM, dual 500GB or 750GB drives and a Blu-ray burner. Also on board is a premium sound system from Dynaudio, four USB ports (two of the 3.0 variety), Gigabit Ethernet, VGA and HDMI sockets and, of course, 802.11b/g/n WiFi.
