My desk top will run everything out there....knock on wood.....but my lap top only has a video chip set. Is there a video card that can be added to a lap top to bring it up to speed? either internally or externally.

Not usually, no. Even if your manufacturer offers the option then it will cost a lot of money, as they'll need to do it for you.

TTBOMK, only Sager still sells a few older style (thick, heavy, bulky looking) desktop replacement machines assembled the old way, more like a desktop. Any others that offered upgrades to either the CPU or the GPU were replacing the entire motherboard at the same time. They are welded together (chassis and MB) too permanently to reuse the old one after breaking it back apart. The simplest thing is to buy either a used laptop, or a really cheap one, and not expect anything from it other than plain business-type work. The money otherwise wasted on extra laptop bells and whistles is then usable for your desktop tower.

On laptops, the components are soldered directly onto the motherboard. Unless a laptop is specially made to be upgraded, like on the Sagers as mentioned above by Gorath, the only option is to buy a new laptop.

If the laptop has an ExpressCard slot, there is a way to utilizing a desktop video card for the laptop through external video card adapters...but it's not a cost-friendly route:

That's just for the adapter. Video card is bought separately. Also, I would think there's some bottlenecks with the ExpressCard slot so you may not get full performance potential with the video card depending on what it is.
