ATI Radeon X1950 XTX 512MB DDR4 Performance Preview
 

Even with 4xAA turned on, the X1950XTX is still the winner in all 6 games, but the margin between the X1950XTX and the 7950GX2 seems to have shrunk a bit. The X1950XTX is overall 15% faster than the 7950GX2 on average, and 19% faster than a X1900XTX on average. It also does seem to me that the Catalyst 6.7 drivers seems to have boost gaming performance quite a bit.
