The subject of this review is ASRock's new Core 2 Duo (LGA 775) ready motherboard called the 4Core1333-eSATA2 R5.0. This motherboard is based on a heavily tweaked Intel P31 & ICH7R chipset architecture and has been modified so it can support just about any C2D processor from the older 800MHz FSB to the newer 1333MHz FSB CPU's.
