I built a PC that runs Windows 7 64-bit. Everything seemed fine initially, but Device Management lists my graphics card as a Radeon HD 4800 series. I have an HD 5870. What's wrong/how can I make my computer recognize the card?

Are you 100% sure? I know that sounds harsh, but mislabelling has been known to happen. – ChrisF Mar 8 '11 at 13:33
windows 7 64 bit. it is definitly a 5870 because it the only part thats not new, been using the card for years – neil harper Mar 8 '11 at 13:36

It might be a 4870, the 5870 has only been out as @Kyle pointed out, for a year and 6 months. – paradd0x Mar 8 '11 at 19:04

Go to AMD Support & Drivers and enter the required values in the section "Download Drivers" and click the button "View results". Or, as you have now entered your OS version, go straight here.

Once you have downloaded the right driver, install it and then reboot.
