PowerColor X1300 Video Card Review


Installing this card couldn’t really get any easier. It was a simple matter of shutting down my machine, opening up the side panel to remove my current video card, and then popping the x1300 into the now vacant PCI-E slot. Secure it with a screw and then proceed to put the case back together.

As always, after installing a new video card you are required to install the necessary drivers for said card. After removing my old Nvidia drivers, I installed the new ones for the x1300 which where supplied on the CD.

After getting those all installed and rebooting my machine, I checked on the Powercolor website for a driver update, and upon finding one installed that as well. As It is always a good idea to have the latest drivers possible. Now of course I know you're itching to know how this card performs so let’s get to the good stuff!
