Laptop video questions

[xvxdarkknightxvx]

I'm lookinh for a laptop, and I'm somewhat confused by a few of the terms manufacturers use. While configuring a Gateway laptop, I came across this describing the laptop's video capabilities. "Integrated Intel® graphics with dynamic video memory technology. Up to 64MB of video memory is available to use with 256MB system memory standard." What exactly is dynamic video memory technology? The Gateway site doesn't have a helpful FAQ that answers this. Also, perhaps I'm under the wrong impression, but I assume that Intel integrated chipsets suck, no matter how much memory they have.

I've also been seeing "shared video memory" a lot, but I've learned that they're a drag on the system memory and are also slower when compared to actual video card RAM.

Would getting a laptop with an actual card like the "64 MB shared memory ATI Mobility RADEON 4X AGP graphics and 3D architecture" be better than getting a laptop with 64 MB integrated Intel video? I'm not exactly sure how they stack up against each other.

I should also probably mention that I'm getting a laptop with no less than 512MB system RAM running Windows XP.
