I'm currently working on a university project, based on the implementation of FFT on a FPGA. My professor told me that the first step is the choice of the correct (or the most suitable) board. Unfortunately i don't know how to make the best choice in terms of memory, DSP blocks and so on. Obviously i have to take into account the price of the board itself.
Could you give some hints ?
Thanks in advance.

One thing you might do is to look into the XIlinx FFT IP cores and see if they
publish the typical usage data for LUTs FFs BRAMs DSP48s etc. Then you
can get an idea how large an FPGA you need from the first few pages of
the FPGA family overview. If you're cost-conscious I would recommend
a Spartan-6 based board, or possibly Spartan 3A DSP.
The other obvious issue is how you need to get data into or out of your
FFT. A large part of board selection is making sure you have the
required interfaces (PCIe, Ethernet, USB, etc.).
Then go to the "boards and kits" section of the forums and search for
items of interest. Not all boards and kits are available directly from
XIlinx, although there is a good selection at least for newer FPGA
families. See if others are looking for the same features you need
and if they found a solution.
You might also want to download the Xilinx Document Navigator.

You can have a look at below Product Selection Guide.
Go to page 27 for the board list.
If you have picked up some boards in your interest, you can go to our webside to get more details about that board.
for example, you can go to www.xilinx.com/ml605 if you want to see more details for ML605 board.
