I work for SolarCity.com and we had just over 600 customers last year for the residential Energy Efficiency services. For each customer we do about 20 different simulation runs to model the effects of changing out various components (like upgrading an old furnace, water heater, etc). Our server has 48 processors of 1.7 GHz and 32 GB RAM. Even with all of that, our single-threaded simulations take a few minutes (we run the 20 tests in parallel). I wonder how it would do on a smaller computer...
In general, I would go with both more CPUs and more RAM, not just for E+ but for other software as well. Your pc is less likely to get stuck if one process bogs down one of many cores. And most tasks, multiple tasks benefit from more RAM. A 64-bit system can support more than 4GB of RAM, if the board supports it.
