First, why do you want a laptop as opposed to a desktop?

Second, what's your budget?

Although I opted to buy a laptop for my latest (2years old now) "gaming rig", I agree. Build a desktop and be happier.

Although I envisioned less wife-aggro by being able to sit with her on the couch, gaming while she watched TV, practice has not lived up to vision. In either case.

If you are lookng for Laptop GraphicaCards check out this site it gives you the benchmarks or the cards:

One of the 2 best cards out for laptop gaming is Nvidia GTX 680M and AMD HD 7970M. 

I currently purchased a laptop from IBuypower.

You're going to be most restricted with your options based on your budget, which you didn't mention.

Almost all GPU's have a mobile version typically designated with an "m" at the end of the model.  They don't perform quite as well as the desktop versions, and aren't usually supported "officially" by game devs, but they are more or less as adaquate for most things.

As for a "list" of laptops, again, you just have to familiarize yourself with what's available at your budget level.  Most OEM's (Dell, HP, etc) let you customize the laptop you are interested in, including the GPU.

The main thing to keep in mind is that, with GPU numbers, higher is not strictly better.  A GeForce GT480 is better than a GT520, for example.

For nVidia cards, start here:

For ATI, start here:

http://en.wikipedia.org/wiki/Radeon#Nomenclature

In both cases, you'll notice that the first number denotes the "generation" of the card, where higher is better.  The rest of the numbers indicate the performance of the card within that generation.  In my previous example, the GT480 is better than the GT520 because the 480 is built for gaming performance, and the 520 is build for basic workstation use like internet and maybe some movies.  In a way, it's like comparing an 1992 Porsche to a 2012 Kia.  One is newer, but the other has better performance.

Anyway, sorry for getting into too much detail there, but serious check out the naming section of the links I gave you.  From there, just go to Dell or whatever OEM you want to buy from, and pick a laptop that's roughly in your price range, or slightly below it.  Then go to "customize" and see if they offer a better graphics card, which they usually do on all but the cheapest models.
