For most of 2007, the P35 was the primary chipset for use in LGA775 motherboards.
It was very versatile, supported both DDR2 and DDR3, and many motherboards, mainstream and high performance, were based on it. We've seen three new Intel chipsets since late last year, the X38, the X48, and most recently the P45.
Its easy to figure out the X48, as it is basically an X38 with capability of running DDR3 memory at speeds of over 1600mHz, but comparing the X38 and P45 gets a little confusing, as they are so much alike.
I'm assuming that the X38 was intended for high performance rigs, and the P45 is the real successor to the P35, the all-around chipset to be a platform all types of LGA775 motherboards, from mild to wild.
