The 800 series got renamed to the 900 so the desktop and mobile gpu names would match up. (Which is why I'm bouncing waiting for the Asus 970 to come up to upgrade from my 570)
Unless you mean the AMD cards. *head tilts*
No, he was just incorrect.
As for replacing the card, yea, they are right, you should def uninstall your drivers and then get naked before you put the new card in.
jk, but it's not too much. Once you receive your new card:
- go here and download the latest 900 series drivers, leave it on desktop
- Uninstall Nvidia PhysX System software
- Uninstall Nvidia Graphics Driver
- reboot - let the basic gfx driver auto-install
- shut down, unplug the psu
- remove your 570
- install the new beast (make sure its fit tight, is untouched, power connecters are snug, and has good airflow)
- plug in psu, power up, install the new drivers you left on desktop
edit: re: the PhysX and Drivers, I'm assuming you only install those 2 sections for your drivers. Unless you have a 3D screen and use the hdmi audio out, and use the GeForce Experience as well.
