ATX motherboards have many advantages over Micro ATX motherboards, such as greater PCI and RAM, which allows multiple GPUs to be installed simultaneously, creating a powerful portable workstation. Fill every RAM slot with high-speed memory sticks and populate expansions using the given PCI expansion for high-end Graphics Cards. Micro ATX, on the other hand, has a fair amount of evaluation and therefore it offers an excellent value. Compared to other compact rigs, it can support half the RAM slots and GPU mounts. Thus, micro ATX uses less RAM and space than ATX, but can still game like ATX.
