HI guys ! I have a question. What should i do with drivers because i had 750ti and now i bought 1070 ? Do i need to uninstall drivers from 750ti and then install drivers from 1070 or will GeForce Expirience do it all for me ?
Recent AMD drivers allowed me to go from a HD7770 to a HD270X to a RX480 without batting an eye. So, if Nvidia's drivers aren't worse than AMD's, you merely need to check if your current driver actually supports your new GPU; if it does, you should be able to shut down your computer, swap graphic cards, and boot - Windows 10 will boot in VESA mode and after a few minutes load your current driver for your new graphics card; and THEN Geforce experience may prompt you for an upgrade.
However, I have had bad experience with Nvidia drivers this past couple years (a GTX1060 would crash hard until I performed a complete driver purge), and I strongly recommend you use Display Driver Uninstaller (available at guru3D) to clean up all your drivers completely before you try and install the latest driver version.
