NVIDIA GeForce GT 640M review
If you look to the right of the review over at the NotebookCheck website you'll notice a long vertical column of graphics card listed. For comparison, there are some desktop cards mixed in about where they lie in terms of performance.
GeForce GT 640M is near the top of what they call Class 2 cards - fourth down the list in that category. If you move up above Class 2 you'll find the desktop HD 4850 fourth up from the Class 2 heading.
