This will be a deciding factor on the laptop that I will choose to buy, both have relatively the same specs except the graphics card. I’ve googled a comparison with no results, and I don’t really know how to compare them myself. So which is better?
Thanks 
I think you’ll find these two articles interesting:
NVIDIA GeForce GT 540M - NotebookCheck.net Tech
ATI Mobility Radeon HD 5850 - NotebookCheck.net Tech
According to the 540M review, “The performance of the 540M lies between the Radeon HD 5650 and 5730 in our first benchmarks.”
Great Information! Thanks for the find!
