Which is the Best Mainstream CPU?
 

f you're looking to buy a new system or a new processor, then you've come to the right place. A lot has been going on in the market, though Core 2 Duo is still the best choice, and AMD still has no technology to fight back. Its quad-core processor called Phenom is positioned to be a show-stopper - we will see. Then again, we've seen substantial price cuts that put even high-end processors at prices below $200. It's time to have another look around.
