I have an old Area 51 7500 which needs upgrading from a 8600 GTS to AMD 6670. I have encountered many problems so I would really like to know how I should go about it in the best way. How would I install the new GPU properly? Do I remove all traces of the current Nvidia drivers, software etc then swap in the AMD 6670? Is it compatible with the motherboard? So I need to change settings in the BIOS?
Dear, it is not that hard.
Download the latest drivers of AMD 6670 from the manufacturer's website for Windows 7 (32 bit or 64 bit whichever you are using).
Update the BIOS [optional step]
Unplug the old GPU.
Plug in the new GPU.
Boot the PC login to the windows.
Uninstall the driver of old GPU
