While it’s generally not needed for a general purpose Linux computer, when editing large RAW files it helps to have lots of RAM. But the biggest reason I upgrade the RAM on SuperMario was that Crashplan requires about 1GB of RAM per 1TB being backed up. With me moving everything but gaming over to SuperMario, I have 4.8TB of data to back up! It had been failing its backups and now, with 24GB of RAM it works quite well and I’m getting close to having everything backed up! Plus, there’s a lot less swapping of programs in and out of RAM!
