Since it was teased in March, enthusiasts have been itching to see how Intel's 8-core Haswell Extreme Edition processor (the i7-5960X) performs. It has now launched (along with two other Haswell-E models) and the reviews are in. Yes, it's the world's fastest desktop CPU -- but the general consensus is "it could have been better." Why? Because Intel recently launched a "Devil's Canyon" CPU for $340 with a base clock speed of 4.0GHz that can easily be overclocked to 4.4GHz. The $1,000 Extreme Edition chip, on the other hand, has a base clock of 3.0GHz and max turbo speed of 3.5GHz. Since clock speeds are often more important to gamers than multiple cores, that might disappoint many a Battlefield 4 player. On the other hand, with DDR4 support and eight cores (Intel's highest count ever on the desktop), the chip should excel at pro tasks like 4K video processing and 3D rendering. Given the price tag, that might be the only market that can afford it. Here's what the experts think.
