"This is a review of the Gigabyte GA-P67A-UD4-B3 motherboard which is equipped with a (new) 'B3'-stepping Intel P67 chipset. The Gigabyte GA-P67A-UD4-B3 motherboard replaces the original Gigabyte GA-P67A-UD4 model that was recalled due to the Intel 6-series chipset issue. This is a mainstream ATX motherboard with a great set of workstation features and connectivity, all on a sleek matt-black PCB that looks fantastic in black computer chassis. The board supports 32nm socket LGA1155 2nd Generation Intel Core i3/i5/i7 2xxx-series 'SandyBridge' processors, such as the Core i5 2500K, and can handle dual graphics cards."
