I recently bought a laptop that has a 6520g integrated card and a 6650M dedicated card. AMD Crossfire is using the 6520g as the primary card, although the 6650M is the better card. This is probably to save power. However, I want to make the 6650M the primary card, and I can't figure out how; I've updated my driver, but there's no option to make the 6650M the primary card. I've searched the BIOS too, and there's nothing there either.
I'm using a Lenovo Ideapad Z575.
Laptops, unlike DIY computers, works better with supplied drivers. IMO, unless you have problems with laptop & recommended by the manufacturer support ( downloaded from their own website), supplied drivers should not be replaced with generic ones.
