This is a supposed leak so we cannot say for sure if it is real. Anyway,the Core i7 990X is SLOWER than a Core i7 2600K in PCMark Vantage. Looks at this article: http://www.tomshardware.co.uk/core-i7-990x-extreme-edition-gulftown,review-32126-4.html A 3.46GHZ six core Core i7 990X is around 20% faster than a 3.2GHZ Core i7 960 in PCMark Vantage. The Core i7 990X is 8% higher clocked than the Core i7 960 meaning that the additional two cores are adding 12% to the score and on top of this the Core i7 2600K is still faster. PCMark Vantage does not scale well beyond 4 cores.
