I'm pulling my hair out! Where the heck can you buy 2 CrossFireX Bridge Interconnect cables?

TomsHardware had a write up on SAPPHIRE HD 4830 running in Crossfire, there was also a writeup on ASRock P45XE LGA 775 Intel P45

I knew when I bought the 2 video cards that they did not include the crossover cable. At the time I had plans to purchase 4 monitors, however I found a sweet deal on 2 1080p monitors.
"""Our only real complaint about the pair is a lack of a CrossFire cable with the cards--on a board that supports the feature, these should really be part of the package""""

Now I can use Crossover, but where to get the cable?
I found several at newegg, tigerdirect and the ATI store, but they are not... ATI CrossFireX Bridge Interconnect cable
They do not list the 4800 series

http://www.newegg.com/Product/Product.aspx?Item=N82E16814999008
Applicable models for ATI CrossFire Bridge Interconnect Cable
HD3870 & HD3850 Series
X1950 Series
HD2600 Series

http://www.newegg.com/Product/Product.aspx?Item=N82E16814999002
Applicable models for HIS CrossFire Bridge Interconnect Cable
HIS X1950Pro PCIe Series
HIS X1650XT PCIe Series

Sapphires website states "The CrossFireX Bridge Interconnect cable is an optional accessory"
Of course, they list no way of actually obtaining one, not do they sell a 4830 with one.

Before you say anything... I'm well aware I need 2!!!

So please.... Can someone explain to me the crossover bridge.
Is a bridge a bridge a bridge? or do certain models have different connectors?


Thanks in Advance

I sure would love to hear a definitive answer to this question, as I too just purchased dual Sapphire HD4830's and the ASRock P45XE.

Based on the reading I've done, I believe CrossfireX is just the terminology for three or four cards in a system and that's there's not a specific bridge for CrossfireX and Crossfire, merely the position of the bridges and cards (two bridges across Card 'A' and 'B' in Crossfire, or one bridge across Card 'A' and 'B' and one bridge across Card 'B' and 'C' for CrossfireX), but again, that's more of a guess.

I would ebay that one. A bridge is a bridge, they are all the same to my knowledge.

NO no, it used to be just crossfire but ATI changed it to crossfirex. Nothing special.

If you need that warm fuzzy security blanket listing for a 4870...
