DELL INSPIRON can run the game without any lag and it is not very expensive, make sure to check it out.
You might want to try eBay. This one has a discrete NVIDIA graphics card (most laptops have crappy integrated graphics cards). It also has a slot loading DVD drive.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
