There's a Gigabyte unit now for $469.99 + DiRT 3. Also the Powercolor 7950 & 7870 for $379.99 & $329.99 respectively both with DiRT 3 are very enticing.
The prices of the 7870 weren't mentioned to be changing in the press release about the price drop but they went down anyway. I was going to gladly pay $350 for a 7870 but now for just a few bucks more I'd just get a 7950.
Hurry up with your competing products NVidia! Can't wait to see if prices get even lower when they come out.
My last Nvidia GPU was the 8800GTX but if they come out with faster for these same price points I'll probably go back to them as I like the Adaptive Vsync they recently implemented and have no need of compute performance.
