Hi

Want some input about a laptop that can run some games. Which graphics card is better, NVIDIA GeForce GT 540M or AMD Radeon HD 7690M?

Looking at these sites to compare but the numbers dont say anything to me, how much difference there is.

Based on my experience with a Lenovo Y470 that has an i5-2410m and nVidia GT 550m, I would go with NR2 which has an i5-2450m and Radeon HD 7690.

At least based on the charts the Radeon HD 7690 is slightly better than my GT 550M. A quad core is nice, but since the vast majority of games are limited to 2 core and the fact that the Radeon HD 7690 is the most powerful of the three listed, you will get better performance with that than a quad core i7 CPU with a weaker graphic card.

Even on a 1366x768 screen you are basically limited to medium quality graphic settings with the HD 7690 in current games if you want good frame rates; at least 35 - 40 FPS.
