MSI : MSI GX623, GX633 Laptops with "Turbo Drive" Technology

These are definitely not MSI’s first Turbo Drive powered PCs:

Exclusive Turbo Drive Engine Technology - CPU Turbo Mode
With MSI's exclusive Turbo Drive Engine Technology, while the GX633 is in AC mode, just by touching the turbo button above the keyboard, you can simultaneously increase the speed of your CPU, also the computer may run smoother and to the best of its abilities.
*The test result differs under different testing environment

And despite not so impressive performance boosts, MSI keeps introducing notebooks featuring a Turbo Drive button, like the GX623 and GX633.

While there aren't many differences between these two PCs when it comes to design (same 15.4” LCD, color…) they feature different specs like a Core 2 Duo CPU and an ATI Radeon HD4670 with 512MV of VRAM on the GX623 and an AMD Turion X2 with an nVIDIA GeForce GT 130 (512MB of VRAM) on the GX633.
