What about real gaming?

The integrated chipsets from NVIDIA perform well enough here, for their class. The GeForce 6150 is almost as fast as the ATI Radeon Xpress 200 even in Half-Life 2 which is evidently optimized for ATI’s graphics processors. So, the only game where ATI’s chipset gains a pure victory is Far Cry .

It should also be noted that the effective difference in performance between the GeForce 6150 and 6100 is less than 8%, although their graphics core frequencies differ by 12%.
