Re: Switching nVidia drivers?

Running Fedora 20 and currently have akmod-nvidia-304xx xorg-x11-drv-nvidia-304xx kmod-nvidia-304xx bits installed. I'm considering changing my video card to a newer one with dual DVI outputs and thinking I'll want to switch to akmod-nvidia, xorg-x11-drv-nvidia, etc to get the 331.38 branch of drivers. Any recommendations or gotchas on the procedure to achieve the switch?

Thanks, Ed
