I never had a problem with just installing over the old ones.
I used to uninstall them, run a sweeper and so on... but to me, it's pointless unless you run into some problems.
Untill I run into a problem later on, I just install over the old ones.
I have this card coming tomora too and installing it prob tues on the sly. Will bench my Gtx 460 and then this after to try justify my huge cost to switch up.
Do I remove all nvidea stuff? I read somewhere that you can still install PhisX and have physics in games just your CPU takes the load rather than GPU. Is thi right?
Fingers crossed now AMD drivers just released that they aren't too flakey and gaming goes smoothly. I know loads of people have 7850's and 7970's, just hope AMD shows the love and support for the 7950's cos couldn't justify the extra cost when gaming at 1920x1080 and hope it lives on for a while and is much better than my GTX460 that I have really enjoyed owning.
