Radeon Mobility HD 5000 series

What is the difference between the Radeon Mobility HD 5000 series and 4000 series? I know the 5000 supports DirectX 11, but how is this a good thing? What is new? I've heard of Eyefinity, but I don't see how that and DirectX 11 will help at all on a laptop.

5. 3 monitor support
6. Dx 11 for newer games that will support DX11 greater eye candy and gaming
preformance, as well as Photoshop and any graphically demanding programs.

As far as helping a laptop it depends on the laptop and the CPU, amount of memory and type either DDR2 or DDR3
And on the GPU DDR5 or GDDR5

The 5 seire cards work with a different chip design for lower power consumption and greater battery life.

I use Nvidia so hopefuly an ATI member can better answer your questions and correct or add to any things in this post.

You have an exceptional laptop but it will never provide the same gaming experience as a comparable Desktop,where you can change the GPU/CPU.
