After checking on here I found another post with someone who had had the fast moving heads issue and they solved it by turning v-sync on in the game's graphics settings. I did this and the fast scrolling, car rotation and heads was solved. Also, the noises from my GPU stopped.

Try tweaking the hardware acceleration:
Click Start in the lower left corner of Windows Vista.
Click Control Panel, click Appearance and Personalization, click Personalization, click Display Settings, and then click Advanced Settings.
Click the Troubleshoot tab, and then click Change Settings.
Note: Change Settings will be disabled if the graphics card drivers do not support disabling hardware acceleration.
Move the Hardware Acceleration slider until it is one notch to the right of None. This is the basic acceleration setting. You can also try it at different stages thru the slider too.

You can use a program such as Cpukiller3 - that way you can slow your CPU prior to playing and then when you've finished, just switch it back up to normal again.
