| The Bottom Line | The CPU market is due for a lot of upheaval over the next 12 months, so you might be wise to wait for a clearer picture before plunking down $1,000 or so on Intel's new Core 2 Extreme QX9650 quad-core desktop processor. But if you want to claim ownership of the fastest multicore CPU around today, look no further. | Thanks to an expensive new motherboard requirement, Intel's new Core i7 desktop processors will remain enthusiast and professional-level parts until more affordable complementary hardware comes out later next year. Speed never comes cheap, however, and if you're willing to spend for it now, you'll find yourself in possession of the fastest CPU on the market. | The quad-core Core 2 Extreme QX6850 keeps the desktop CPU performance belt tied firmly around Intel's waist at a price that helps offset the lack of sizable performance gains. New products at the end of the year may outclass this new chip when they arrive, but for now, the QX6850 reigns supreme. | We recommend the AMD A8-3850 to mainstream desktop PC users in search of capable gaming power and multithreaded application performance. | AMD's Athlon 64 FX line has worn the desktop CPU performance crown for over a year. The king is dead. Intel's new flagship Core 2 Extreme X6800 not only hands AMD a defeat on all of our benchmarks, but it's also a more efficient, better designed chip overall. |
