The 540M is a bit slower than the desktop GT430, while the 6570M is about the same as a desktop 5570, based on the specs.

Check this review for a comparison.
There are two types of 6570 and 5570, DDR3 and GDDR5, that Anandtech review shows the slower of the two (DDR3), so that's a worst case scenario. If the card you are looking at is GDDR5 it will be faster, but it's more likely ot be the DDR3 version.

The 540m has 2gb if that matters.

Lonyo gave you the answer already. Plus 2GB of VRAM is a total waste for a card of this level.
