GIGABYTE GA-EP45-DS3R Motherboard   Enthusiasts have experienced a rash of motherboard chipset releases as of late, with no shortage of such releases coming from the Intel camp alone. The new introductions have ranged from the X38, X48 and the P45. Compound that with the fact that both DDR2 and DDR3 flavors generally exist for each, and you have a large number of models making their way to the market. The P45 can be considered the spiritual successor to the P35(die shrunk from 90nm to 65nm), while playing host to a slew of new features. Intel's P45 chipset, codenamed "Eaglelake" is designed and aimed at the mainstream and performance market. The P45 chipset also brings Intel's ICH10R Southbridge to the table, and supports the latest Intel 45nm processors. Rounding out the P45 feature list is support for 1600 FSB, and DDR2 ram up to 1200Mhz, and DDR3 ram up to 1600Mhz. The only potential downside to the P45 variant, is that while two PCI Express 2.0 x16 slots are provided, as soon as you utilize a dual GPU configuration, the x16 slots will work at the speed of x8. However, this is most likely not a limiting factor, as most Crossfire configurations will not oversaturated a dual X8 bus. It comes with the following: INTEL Q9550 INTEL CORE 2 QUAD 2.83GHz/ 12M/ 1333/ 05AL835B399 And Patriot Memory 8.00GB DDR3 1600MHz
