Switching nVidia drivers?

[Ed Greshko]

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
