Intel Core i7 990X Hexcore 1366

Intel Core i7-990X 


With so much hoo-hah surrounding the P67 chipset and the performance thereof, the X58 boards have been left somewhat in the shadows.

Not, by any stretch of the imagination, because that’s where they belong, but rather the twin terrors of pricing, and target audience, have meant that your average consumer is much more taken by the “my first overclock” nature of the LGA1155 equipment than the enthusiast based LGA1366.

Despite this there is enormous amounts of life in the old girl yet and most of the big scores and jaw-dropping overclocks are dominated by the original Core i7.

With the forthcoming Socket 2011 on the horizon, Intel have brought their knowledge to bear on a swansong, a bit of an encore if you will. One last hurrah.

In exactly the same way that your favourite band doesn’t play all their hits at the start of the show and their encore consists of a couple of b-sides from their days gigging in pubs that nobody have ever heard, Intel aren’t going out with the whimper of a dual-core, non-HT revision or anything so watered-down.

No, today we have the all-singing, all-dancing, eye-wateringly pricey Core i7-990X Hex-Core to get our teeth into.
