i have hd 7750 and a8 5600k apu processor, but when i installed catalyst, there's no option to enable crossfire. I only can enable dual GPU on BIOs, but still no option for crossfire. How can I properly configure my PC for crossfire?
 
You won't see a massive performance increase because the HD 7750 and HD 4850 are pretty much on par that way but you will be able to play DirectX11-only games that aren't supported by the HD 4850 because it only supports up to DX10.1 although you will see a major drop in power use, noise and heat. The HD 4850 was a VERY hot card, hotter even than one of my HD 4870s.
