With NVIDIA having taken the performance crown in the graphics card market once again, the best response AMD/ATI could give (short of introducing a new card to market) is by reducing prices on its existing flagship model, the 4870 X2.

And it appears the company has chosen to do just that. XBit Labs reports that a $100 shaving has taken place on the MSRP for the model this week, shifting from $549 down to $449. It's also been mentioned that some partners are further offering $50 mail-in rebates for their 4870 X2 models when purchasing through Newegg.com.
