Minimum Requirements:

• Who knows! Every computer I ran this on was fine.
• I ran this on an EEEPC 901(~US$500, 2008) with 2GB RAM running at 800Mhz ("power save" mode). it didn't have any problems.  
• I even managed to make it work with software rendering under a virtual machine
• Can you run it on anything less? Let me know!
  

Limitations:

• General: Currently you can load approximately 2/3 of your system RAM's worth of data at any time;
  • You can load files larger than this, just not all of it at once (subsets or samplings).
• 32 bit versions:
  
  • General: You can only access files up to 4GB in size.
    
  • Windows :  You can only access up to 4GB of system RAM in the application, regardless of how much you have
    
• Most, but not all state files can be transmitted between differing 3Depict versions
