As some of you may have know, I'm doing a video card migration from a 7900GS to a 5870, as per my long lifecycle deal.
So here is the steps I think I should be using to migrate it.
OS is windows 7 RC 7100 64-bit
remove nvidia drivers from programs with it's own installer
reboot with nvidia card into safe mode
use driver sweeper from guru3d (only one that works on windows 7 64 I think)
shut down, swap cards
install newest cata drivers.
So a few other things, I have some games that needed the phyx thing installed, do I need to remove those, or are they vender neutral still after nvidia brought them out?
and would the steps be similar to the one above? Just remove the phyx driver/program and then run sweeper in safe mode?
Lastly, for OCing, do I need a special driver or are there separate programs like riva tuner for nvidia that I can use for OCing. my last ATI card was the 9200 and that was a long time ago where I have no idea what OCing was.
Depending on which games, they should work, but they won't look quite as pretty (in reality they will look prettier since you're going to a 5870). As for OCing, there's always catalyst and amd overdrive, but they don't always work; ATI tool hasn't been updated in years, and doesn't even support the HD 4000 series cards, so they probably won't support 5000 series without a new version (current is 0.26). With that said, I use rivatuner to OC my 4870 (I know, its called "rivatuner" but it still works on ATI hardware). It might take a new release to support the new architecture, but you can always give the current version a try.
