Radeon X1900 XTX 512mb EDITION

Spotting the differences between a X1900XTX and X1900 Crossfire Master card from the top down view isn't particularly easy. Both cards are very similar in design and the components which differ are mostly hidden away under the cooler.

Flipping the card over and the similarities continue

Where the card does differ though is the connectivity. The PCIe bracket for the XTX features dual DVI and video out to feed whichever displays you use.

Of course just looking at the card doesn't explain all the differences and so it's the specifications that you need to consider here. The XTX uses the same R580 core as the X1900 Crossfire card however the XTX has clocks set to 650mhz core and 775mhz memory (again connected to 512mb GDDR3).
