NVIDIA GeForce GT 540M: Mid range graphics card based on the GT 435M chip (GF108) with higher clock rates and theoretical support for GDDR5 (always used DDR3).

These cards should be able to handle all current games with fluent framerates but not all with high detail settings. Especially demanding games may only run in low-medium detail settings. However, you can get some cards in smaller form factor laptops with good battery life.
