Radeon X1800 and Xpress 3200 might allow Crossfire without Master Card
 

There seems to be a strategy to extend the value to those people that have shelled out for X1800 parts, by allowing Crossfire to work without master hardware, but only on Radeon Xpress 3200 -based mainboards.

It's set to be announced after CeBit, and looks like being workable with the entire X1800 range, from XL to XT and possibly All-In-Wonder to boot. With X1800 XL at £170 just now, which seems to be price competitive with GeForce 7600 GT, X1800 XL Crossfire without master hardware suddenly looks mightily attractive.
