In this respect, P45 provides something new, allowing discerning gamers building on a budget the opportunity to experience multi-GPU 3D graphics acceleration without the need for an absolute top-end motherboard. Unlike G45/P43/G43, P45's PCI-E 2.0 ports can be configured for either 1x16 or 2x8 operation, which is different from past mainstream/performance segment chipsets like P35 and P965 where it was impossible to directly connect more than one add-in graphics card to the Northbridge PCI-E resources. How much that actually impacts dual-GPU performance is still a topic of debate, as the PCI-E bandwidth generally does not seem to be the major limiting factor. However, unlike X48, P45 only provides 16 PCI-E 2.0 lanes, so AMD/ATI CrossFire setups will only receive half the bandwidth relative to an X38/X48 board. Intel 4 Series chipsets are fully PCI-E 2.0 compliant, which increases the maximum theoretical bandwidth of any installed PCI-E 2.0-enabled component by a factor of two. PCI-E 2.0 Graphics and CrossFire(X) Support As an aside, with the exception of X48, all Intel 4 Series Express chipsets are officially able to address up to 16GB of DDR2 memory (but only 8GB of DDR3), making G43 an attractive candidate for consideration when it comes to assembling a 64-bit single-socket budget server. Individual motherboard manufactures are also free to develop products that feature an Intel 4 Series Express chipset and legacy DDR2 memory technology for consumers looking for low-cost alternatives to more expensive DDR3 modules.
