Finally a graphics driver for my 4870x2 card! Thank you SO much!!! Edit: just to add there wasn't a Display Adapter listed on my PC, so I had to choose one of the display devices that had a question mark next to it and update the driver from there... in fact I had to do it twice, with the VGA compatible display device too. Then it worked, although it's 16 bit rather than 32 bit colour depth only, but hey, it's better than 640x480 8-bit graphics eh?
