Is DSP Development Kit, Stratix III Edition the right choice?

Thanks Dave, I found the dev kit solely for Stratix III.

Basically I need to build a real time embedded system:-

to read signal from high speed ADC (~400 mega samples per second), then track certain value and save to 'A' and also write the waveform into text and save into storage device B.

So, it must be able to do multiple tasks in parallel at high speed:-

1) interface with USB Flash Drive

2) interface with PC and other instrument through MAC and RS232 or I2C etc. (common interface protocol between IC)

3) interface to RF link device such as WiFi and BlueTooth

something like that, it seems to be a customised high end motherboard without audio, video and only for realtime super fast ADC output monitoring, tracking, analysis system with large storage volume capability.
