Intel Gulftown six-core Extreme Edition CPUs are working happily on X58 based motherboards, and most of the new socket B 1366 motherboards already have X58E chipset.

Intel still officially talks only about X58 chipset that was introduced almost two years ago in Q4 2008 and there are no any changes in the official chipset listing at Intel’s webpage.

Some daring companies such as Gigabyte claim that many of their motherboards do have this new chip including Gigabyte MB GA-X58A-UD3R, GA-X58A-UD5 and GA-X58A-UD7.

At this time there is no indication about any changes in the high-end chipset market and we can confirm that the future Core i7 990X Extreme edition fits in the same X58E motherboard. There are no X68 plans, at least not now and they won’t materialize soon.

It looks like that X58E motherboards will have to reach for USB 3.0 support from the third party vendors as two years can do a lot to features inside of one’s chipset.
