I am also sticking with 4GB RAM until the prices for 8GB modules drop. In my newer systems, that allows for a 48GB base but, unfortunately, no expansion without replacement.

At the time we bought our hosts, I felt that the cost to jump from 32GB to 64GB was way too high for the limited benefit it would provide. I added hosts to our setup instead. Right now, we are running five hosts with 32GB and dual Xeon E5450s. What I've been doing is, anytime we need to buy a new system for something outside our virtual environment that will probably be virtualized in the future, setting up the system as close as practical to what I would want in our virtual setup, so that the hardware can be reclaimed as an additional host with little to no additional cost.

I am seeing huge memory price increases as you scale up in amount (4gb dell dimms are about $42/gb whereas 8gb dell dimms are $120/gb). So I am just currious how much memory you use in your virtual hosts and how many hosts you have? Right now we have 2 with 32gb each, at the rate of the price slope, I could almost add a whole new node to the cluster w/32gb for around 8K (or 2 nodes w/32gb for 16K) rather than upgrading both existing nodes to 64gb for 14K.
