My Laptop has 4GB of RAM and I saw recently that Lightroom 5 requires 2GB of RAM but recommends 4GB so all looked ok. I have now seen that it requires 2GB but that 8GB of RAM is recommended, so totally confused and wondering whether the upgrade to 8GB on my Laptop is really necessary. As quite costly I would like to get this right before jumping in on an upgrade. Any help appreciated.
Lightroom certainly works with 4GB, but it will work better with 8GB (and a 64bit operating system).
