You do not have a dedicated graphics chip - you have an AMD coprocessor, which is a secondary GPU that assists the Intel GPU.
The Intel GPU is the only one that is connected to the display panel, so (1) all video data passes through it, even if it has been processed by the AMD GPU, and (2) the Intel GPU will always show as primary. since the AMD GPU is just a co-processor, it cannot serve that function.
This is NOT in any way a high performance graphics system - it should play most games at low- to mid-range video settings. It will not function at high settings - for that you'd need a true, dedicated GPU -- meaning you'll need an Alienware system. None of the inspirons have true dedicated GPUs.
Earlier NFS games up to Most Wanted (2005) can be ran at full settings even with an integrated Intel graphics card. The AMD HD 7670M is fully capable of running Underground 2 at max settings with a resolution at least 1366*768.
The problem is probably caused by the Dell AMD video driver - on recent Inspiron notebooks, if one installs the Dell video driver for AMD, almost all games are unplayable when played on the dedicated graphics card. Installing the generic AMD driver solves the problem, the games become playable, but when entering the laptop in sleep/hibernate, or turning off the internal display, the laptop freezes and only a hard reset can help.
(For example I have a HD 8850M; with Dell drivers the Firefall game gets ~2 FPS when ran with the dgpu on lowest settings, if I run it with Intel igp on the same quality level, it gets ~25 FPS average. With AMD generic driver the same game gets ~60 FPS average on medium/high!)
