Dev.kit with gigabit ethernet

Hello all,

could you advice me some development kit with gigabit ethernet PHY ? I need quickly send data from fpga on-chip ram to pc and when i use 10/100Mb PHY DP83848 i achieve max. 6-7MB/s data flow to pc, but it si still few, because i need to send data to pc and acquire new on chip memory.

Or do you know another methods to quick saving large volume of data ?

Thank you.
