Most of the reviews out were done using 5.10, not the 5.11 with improved memory controller. Theres no way the X1800 XL gets beat out at q4 with the 5.11 drivers. Also, the X1800 XL's overclock like crazy, all of them that ive seen in forums have managed to go from 7200 3dmark05 to around 8500 average. Mine personally is at 8900 and im on a socket 754, and i havent even began to add volts to it yet. IQ is also better on ATI imo, and the drivers have really came a long way.
