Holy Overkill, MSI's X79A-GD45 Motherboard Supports 128GB of RAM!
No, that's not a typo, at least not on our part. According to MSI, this board's eight DIMM slots support up to 128GB of RAM, likely far more than you'll ever need for the life of your system. It's an absolutely crazy proposition for the average user, but for power users who do more than dabble in photography, CAD design, and other types of memory-heavy content creation, this is a consumer-level board with a professional-level work ethic.
The rest of the feature-set is almost standard fare by comparison, and only by comparison. It has five PCI Express x16 slots, a single PCI-E x1 slot, a par of SATA 6Gbps ports, four SATA 3Gbps ports, RAID 0/1/5/10 support, a GbE LAN port, two rear-mounted USB 3.0 ports, six rear-mounted USB 2.0 ports, audio inputs, and other odds and ends, including MSI's Military Class III components, UEFI BIOS, THX TruStudio PRO sound, and an assortment of proprietary utilities.
No word on price or availability, though it's selling in Europe for around $260 (after the exchange rate).
