What is the manufacturer? You seem to think you have integrated graphics and a graphics card in your laptop. Most laptops only have integrated graphics with no add on MMX cards, DELL would be one of the few laptop builders that allow the MMX card to be replaced/upgraded. I upgraded my ATi 9700M 128 Mb GPU to an ATi 9800M 256 Mb GPU but that was the highest it could be upgraded to. The M17x Alienware I have came with nVidia two 280M GTX cards running in SLi and an integrated nVidia 9400 for use while running on battery, I have upgraded the GPU's to two ATi 4870's running in CrossFireX and the integrated 9400 is still utilized when on battery. There are provisions in the BIOS to enable/disable both the Hybrid Graphics and the integrated graphics so I would look to your BIOS, or at least fill out your specs in more detail.
