Two on-board FPGAs - recommendations?

I am looking for a board with two FPGAs on it, each connected to an SDRAM.

Does somebody here use such a board already? Any recommendations?

[I'm not sure if this is a right place to post this question. Please correct me if I am wrong. ]

Thanks,

FPGAkitty

    Can I ask you why two twin FPGAs? Why not a single, big enough FPGA?

    Is there a specific reason to split your design in two identical parts?

    I am interested in the memory bandwidth which would come with two FPGAs each with a dedicated SDRAM. My thought is that a single FPGA - memory system would have half this bandwidth. I could just interface two boards instead, but the pin delays involved would be significant.

    TerASIC also has a new set of boards in the DE3 family that can interconnect.

    Try the distributors (e.g. Avnet, Arrow).

    Most are single FPGA designs, but....
