Is the difference between an Nvidia GeForce GT720M and GT820M that much?

I'm looking to buy a laptop and I'm choosing between a Lenovo and an MSI.

Lenovo S410P 5939-1169
- Intel Core i5 1.6 GHz, 3MB L3
- 4 GB DDR3 RAM, 500 GB HDD
- Nvidia GeForce GT720M 2GB

MSI CX61 2PC-i5047
- Intel Core i5 4200M
- 4 GB DDR3 RAM, 750 GB HDD
- Nvidida GT820M 2GB DDR3

They're almost the same in price. Which one do you think would provide the better graphics performance? Since they're specs are almost the same, I'm guessing that the different graphics card with the higher number makes the MSI faster. Am I right? As of now, I'm more inclined to buy the Lenovo one since I like the design much better and it has a touch screen but will the difference in the graphics card be that much for me to just consider buying the MSI one?

Its a very very small difference, one that you probably would not be able see. Plain in simple it is a slightly faster card but will it save you in a pinch? Probably not.

The difference is 100m
