Intel发布旗舰级Core 2 Extreme后，依然没有停止其前进的步伐。随后Intel将推出采用1600MHz前端总线设计的Core 2 Extreme QX9770系列处理器，与其搭配的则是最新X48芯片组。
华硕、技嘉等主板厂商相继放出了计划推出基于X48芯片设计主板的消息，但最终产品却迟迟没有与消费者见面。截至到今日，华硕终于领先业界推出了首款基于X48芯片设计的P5E3 Premium主板。从型号上来看，它是X38系列主板的延续。
华硕P5E3 Premium主板
华硕P5E3 Premium主板采用Intel X48/ICH9R芯片组设计，支持1333/1600MHz前端总线设计处理器。支持双通道DDR3内存，主板提供4个DIMM插槽。提供3个PCI-E2.0总线显卡插槽，支持CrossFireX技术。板载网络接口。
