| The Bottom Line | 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. | We recommend the AMD A8-3850 to mainstream desktop PC users in search of capable gaming power and multithreaded application performance. | 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. | Intel's Core 2 Duo E6700 offers the best price-to-performance ratio we've seen in a desktop chip. For half the cost of AMD's top-of-the-line chip, you get identical if not superior performance and better power efficiency. AMD surprised us last year with its completely dominant dual-core chips, but Intel regains the crown with Core 2 Duo. | Basic specs |
