Foxconn 975X7AA Crossfire Mainboard 

Manufactured by: Foxconn
Supplied by: Foxconn
Street Price: $210.00

Foxconn has grown out of its original beginnings of an OEM component producer to be a premier maker of high end mainboards.  Their packages can now go head to head with any other tier 1 manufacturer on the market in my opinion and their 975X7AA board is no exception.  Opening up the door to ATi’s Crossfire Technology to the Intel crowd is welcomed by many.  Today, we have a sample of Foxconn's flagship, the Foxconn 975X7AA mainboard on deck.  Aside from our usual perusal of the board in this review, we hope to look at things from another standpoint as well; that of the reluctant user and upgrading.

Until recently, Crossfire and DDR2 haven’t been exactly been heavy draws to the masses for the upgrade of a major component such as a mainboard.  ‘Until recently’ being the operative words here however.  It has only been somewhat recently that it came to pass that DDR2 is going to have an AMD audience effectively solidifying its place in the market.  Likewise, ATi's Crossfire is now mainstream enough that it also is gaining market share.  So is the Foxconn 975X7AA the board to give the Intel followers a reason to pile on with DDR2 and Crossfire?  It’s a big step for many, so let’s see if we can take some of the fear out of things by looking at what Foxconn brings to the table with the 975X7AA.
