High Speed Development Board

Hi, I am working on a 10 Gigabit Ethernet Projet. I have to choose a High-Speed Development Board. I don't know yet which kind of FPGA I am going to use. (Altera o Xilinx).

I saw on Altera's Web Site the "Stratix GX High-Speed Development Board

I saw on Altera's Web Site a second High Speed Development: "Stratix I High-Speed Development

I found the equivalent on Xilinx's Web Site. But I found nothing. Can you confirm me that nothing equivalent of these 2 High Spee Development Board of Altera is realised by Xilinx?
