The Radeon 4870 graphics card is the centerpiece of the recent GPU comeback for AMD/ATI and the entire line of Radeon desktop products. The current 4000 series has apparently sold very well and now proved to be extremely successful with over 2 million cards sold since launch. A new price drop on the Radeon 4870 to just $199 will only help boost those figures.
While there's still plenty of room for argument about which vendor has the “better” card, there's no doubt that AMD has made a complete turnaround from ATI cards a few years ago.
Less than three months ago, the 512MB model of the 4870 was retailing for over $250, but now can be found easily for under $200. The 1GB version will now go for about $240.
