ATI started a $100 rebate campaign for users who plan to get a CrossFire system.
In order to get a rebate, customers should purchase a RADEON X8-series product, register it and get a so-called e-coupon, buy a RADEON X8- CrossFire Edition graphics card by September 29th and then mail in the completed e-coupon and the UPC code from the CrossFire Edition graphics card. ATI promises to send a $100 check within 8 weeks after the company receives the codes.
However, it is still unclear when ATI will launch its CrossFire. The company promised the first Radeon X850 CrossFire Edition cards by mid-July but currently neither CrossFire motherboards nor graphics cards are available on the market.
More details at X-bit Labs who also points out that ATI will need to hurry up a bit as NVIDIA's GeForce 7800 GTX currently thrashes the ATI Radeon X850 XT PE in virtually every benchmark.
