The first, from Guru3D is a Gigabyte GA-G1975X mainboard review.
The Gigabyte G1-Turbo combine the finest from Intel & Gigabyte and have more functions than a Swiss-knife. This mainboard is the firstborn from that G1-Turbo series. Featuring the latest Intel 975X Express chipset, it support the latest Intel Pentium Dual-core & Extreme Edition with an FSB frequency up to 1066MHz. The new 975X chipset is in many ways similar to the 955X but now has official support for dual PCI-E graphic cards for and even better gaming experience.
The second is a Bjorn3D review of the Gigabyte GA-K8N51PVMT-9 nForce 430 Motherboard.
Integrated graphics have had a bad reputation for years, offering performance bad enough to be called "graphics decelerators" by many. Choked by relatively slow system memory and comparatively simple circuitry, integrated graphics have historically been a poor substitute for add-in cards. NVIDIA hopes to reverse this trend with its new GeForce 6150 integrated graphics processor.
