The easiest way to compare two different model boards by Asus or just about anyone else for that matter is simply taking notes on what chipset it has, the cpus it will support as well as the memory to add to that list, and other things like how many pci slots. usb ports, etc.. When buying the A8N-SLI model here last year I could have gone for the A8N-SLI Premium like a friend did due to some other features there. Both were nForce 4 models and my friend received two bad boards in a row? That's a little rare but...?
The actual differences between the first model and the Plus can compared by looking over the specifications on each as seen at the links here. For the P5N32-E SLI model seen at
