Your router/switch/network may very well be the next bottleneck before RAM. With only 3 users any additional memory probably won't even be noticed (most of the time anyway - lots of small files and/or really big files can make a difference) but it sure won't hurt. Buy as much RAM as you can afford, keeping in mind that it almost certainly will be cheaper next year.
