I would highly suggest the following protocol (it may be overkill but then I've also avoided a lot of driver related issues this way):

Download and install DriverCleanerPro (it's a good freeware program)

Now, uninstall your current driver and reboot into windows Safe Mode

Once in Safe Mode, run Driver Cleaner and select multiple filters thereby cleaning all things ATI out of the registry.

Reboot in normal Windows and install the new driver.

The benefit to running Driver Cleaner is that it clears the registry of all the previous driver so that there is no overlap from old to new. I've avoided nasty little issues that have popped up on other peoples computers by using this tried and true method.

I will echo what others have said in this thread:  Build your own desktop. 

Unless you really need a laptop for reasons other than gaming, it is a big money-sink.  My younger brother was in the market for a pc (this was a few years ago), and I told him I would build it for him, etc. but he just "had" to get an Alienware laptop....well, he spent about $2,500 and after a year it couldn't even keep up with the newest games.

If you build your own desktop you'll be saving loads of money and you will get a HUGE bang for your buck.  And building your own computer is not that difficult.  I remember when I built my first rig a 4 years ago I was pretty nervous.  However, there are so many good guides on the internet, not to mention the helpful people on the forums that will anwer your questions. 

 Good luck!
