I have a nVidia GT 640. It needs to be replaced soon. Have been using nVidia since Voodoo 3, as every ATI I've tried in between was never what I expected. As ATI's are normally cheaper and learning BF4 is optimised on ATI, I might give it another try. I must say I will never spend more then €200,- on a GPU (the gpu Andy mentioned ships for €345,- to start with).
