Nvidia Quadro and ATi FireGL are optimized for best performance in OpenGL. This is a graphics library mostly used by the solid modeling/rendering computer applications (Inventor, 3Dmax, ProEngineer, Abaqus, FEMAP etc.). Windows itself can't take any benefit from this video adapter to increase the speed of its own interface graphics (dialogs, title bars, menu fading etc.). Most of the popular games, and lots of the graphics applications are using Microsoft's own graphics library, called DirectX. For DirectX the best performance you can get from the so-called "gaming video cards": GeForce, Radeon. The problem is these are cut-down not to be able to perform properly in solid modeling applications, just to force the users to buy the expensive ones (Quadro, FireGL).
So if you want video adapter for games - go for Radeon/GeForce. If you will do more modeling in an OpenGL application - go for FireGL/Quadro.
Just to mention: if your video-adapter doesn't support something your application needs - this will make the central processor to substitute the video-chip. That means the same work to be done for more time and more heat, as the CPU is not doing the thing in the optimal way. So I would recommend if you have enough money to buy a Quadro/FireGL video.
You can buy a notebook with integrated Intel video only if you don't need to do 3D OpenGL fast. In this case all the work will be done by the CPU. Also note that there is a huge difference between Intel's integrated videos and ATI's integrated one. The last one is times faster and unloads the CPU much more.
Actually the main difference between the "workstation" and "business" laptop is the video-chip. The rest of the hardware is mostly the same, but the "business" laptop usually has in integrated Intel's video, which is done so to lower the price (cost of the video chip = 0) and to lower the power consumption, especially for the power-hungry Core 2 Duo CPU.
The second big (but more visual) difference is the screen: size and resolution. You can see 1920x1200 resolution - that's twice more pixels than the standard 1280x800! It means that you see twice more on the screen - that's a big deal (and big price). But if you have eyes problems (you have glasses) - consider that you might not be able to see the small pixels, i.e. small text, buttons, menus, etc.
In Europe you'll need a thousand Euro for a good CPU/Graphics/Screen laptop. If you lower the price, than some component is getting cheap - firstly this is the screen. The cheap ones will do the same thing for you about 80% of the time, and you'll swear and shout in the rest 20%. It is just a matter of your mind - how you will accept these 20% - you will be wise enough to adapt yourself, or you'll get easy full and frustrated.
Don't buy second-hand notebook with Geforce Go chip, combined with Core 2 Duo CPU - except the laptop weights more than 3 kg. This is because of the overheating for which the cooling system can't cope, because Intel is giving the average thermal power of their CPU - not the maximum one, and the GeforceGO is quite hot too, and the manufacturer of the notebook usually designs the cooling system with only one heatpipe, considering that both Video+CPU will never work on full load together, but the reality is different. So you will end with burnt videochip, because it is not so melt-resisting as the CPU, and the repair is so costly, that you will prefer to buy new laptop.
