Phoronix: ASUS P5E64 WS Professional

Intel's latest performance desktop chipset is now the X48 Express, but there still is life left in the X38 Express, which was released late last year. The Intel X38 and X48 Chipsets share many of the same features including support for the latest dual-core and quad-core Intel processors, DDR3 system memory support, and 2 x PCI Express 2.0 x16 interfaces with there being very few differences to the end-user between these chipsets. In addition, benchmarks we have delivered from different motherboards have shown the X48 has little to no performance improvements over the older Bearlake chipset. ASUS's X38 motherboards are still very much in the market place and today we happen to be looking at one of their workstation motherboards based around the X38. The motherboard we are looking at is the ASUS P5E64 WS Professional, which ships with all of the usual ASUS innovations in addition to having four PCI Express x16 slots.
