Three new chipsets from Intel will be launched in September; the X38, X48 and G35.
We didn't get the final date but we know that the launch won’t take the place at IDF that starts on the 18th.
Motherboard partners already adjusted the prices of the P35 motherboard as the new of will make the previous chipset run for its money especially with DDR3 performance.
The first motherboards with these new chips will be available in September but most of them will arrive in October.
