I work in a law firm where right now I am going through a lot of "ediscovery", to the tune of 40GB worth of emails and other documents in PDF. Searches mostly involve typing in keywords and waiting. I'll usually have about 100 PDFs open at a given time. Right now I am using a Windows 7 PC with a Core 2 Duo, 4GB RAM, and a 5400RPM hard drive. Searches are pretty slow. I'd like to make a recommendation that we upgrade the computer to improve efficiency, but I'm not sure where the bottleneck is. Obviously I am going to suggest an Apple product, but spec-wise, do I want to lean heavy on the RAM? CPU? Will a big SSD be beneficial for these searches?
