May 7, 2009 If there’s one button that could possibly be more tempting than “do not press”, it's the one with “turbo” written on it. Perhaps recognizing this MSi has included a turbo button on its new GX623 and GX633 laptops that ramps up the speed of the CPU when the laptops are connected to mains power. If instead you’re looking for reduced power consumption and longer battery life, MSi’s ECO Engine can cycle through a range of power setting tweaks at the touch of a button.

Both the GX623 and GX633 feature a 15.4-inch display and sport a metallic red racing strip to offset the black aluminum base. The only differences between the two new models can be found under the bonnet. While the GX623 is powered by a Core 2 Duo processor and ATI Radeon HD4670 graphics, the GX633 opts for an AMD X2 Turion Ultra processor and NVIDIA GeForce GT 130M graphics. But that’s where the differences end, with both units supporting up to 4GB of RAM and 500GB hard drive and including standard laptop features such as 802.11 N Wi-Fi and 2-megapixel webcam. Slightly less standard are the units’ HDMI out port, and Bluetooth only included as an optional extra. A Blu-Ray drive is also optional. For jet-setting accountants the keyboards include an independent numeric keypad, while the color highlighting of the W/A/S/D keys has gamers in mind.

Although the GX623 and GX633 are expected to start appearing shortly, there is still no word from MSi on price.
