Hey guys, i finally recieved my components to set up my new computer. I wanted to go with intel and ATI. I recieved my CPU (E8500) and my motherboard ( P5E Deluxe) i wanted to get everything up and running ( while waiting for my 4870 x2 to arrive so i used an 8800 GTS that i had Lying around. With everything running fine, here is my Question or consern.

Will i be able to simply unplug the Nvidia card and plug my 4870 x2 right in. Will i need to unistall the Nvidia drivers first ? or do i install the catalyst drivers before plugging in the new ATI card. Any help or tips would be greatly appreciated. Thanks, Patrick

uninstall the nvidia drivers first, remove the nvidia, insert the ati, install catalyst drivers.

Use a program like driver sweaper and delete the drivers in safe mode, then put your ati in and instal drivers.
