There are 3 different versions of Asus A8N-SLI motherboards, the A8N-SLI, A8N-SLI-E Deluxe and the A8N-SLI Premium. The biggest difference is that the Premium boards now feature the Asus Heat Pipe technology which offers better head room for overclocking. This board has so many features that it should satisfy the most hardcore user out there.
