I just bought my $1,800 HP laptop with 6G RAM, 2.0 GHZ i7 CPU, and a Radeon (TM) HD 6490M graphics card. But for some reason, when I do a system scan of my computer, all it says is that I am using the integrated HD graphics, and thus my games are hardly running.

When I go into my device manager, under the Display adapters it says that I have the HD 6490 as well as the Radeon HD Graphics. I also tried to go onto the Radeon site and update the drives but it says its  not compatible and I need to contact HP to get the mobile versions of the drivers.

Can someone please help me?
