Summary: The only numbers worth mentioning are surprisingly subpar disk I/O numbers and a performance edge in FEAR. The Premium’s one serious advantage over Nvidia’s 780i is still pretty valuable though: validated 1,600MHz front-side bus support, which makes it a far safer bet for anyone who places CPU performance above running two GeForce cards in SLI. But who knows, maybe AMD will do Intel a favor one day by introducing GPUs that people will use.
Pros: Official 1,600FSB support, eSATA, and 802.11n for free!
Conclusion: Up until today there has always been a clear line between the two types of Asus motherboards. The P5* Deluxe/Premium series has always been for those who want a good board at a reasonable price with some mediocre overclocking options and on-board extra's such as WiFi. While the Republic of Gamers series has always been aimed squarely at overclockers. However, with the release of the P5E3 Premium Asus have closed the gap.
Pros: Extensive BIOS options with ability to manually enter voltage selection., Managed 490FSB on our Q6600 chip and 520FSB on a QX9650., 3-phase power delivery to DDR3 slots., Simple but innovative features such as the Q-Shield, Good overall layout., Motherboard jumper to unleash insane voltage options.
