Dual Core & Standard Processor

It's 2 x 2 GHz, making it equivalent to 4 GHz. They work differently, of course. Sometimes a single processor is better for particular processes (I couldn't tell you specifically), while 2 processors will usually get the job done quicker. I have a Toshiba laptop with a Core Duo (first generation, not even second) 1.66 GHz x 2 processor, and everyone else's machine is sooo slow to me. :P I assigned a keyboard shortcut to MS Word, and it opens up before I can get my fingers off the keys! By the way, I would recommend a Core 2 Duo, whatever you intend to use it for. Up until a few years ago, AMD's Athlon FX processors were dominating in graphics, while Intel continued to hold the multitasking arena. But now, the Core 2 Duo processors are beating AMD black and blue across the board. What's really sad is that they do it while consuming much less power (AMD chips waste energy in a huge way). Intel's most powerful processor consumes less juice than AMD's weakest currently on the market. And, regardless of whatever else, Intel uses faster cache memory in their chips. From the pressure Intel has been applying on AMD with counteractive price cuts, compounded with the less-than-impressive performance of AMD's processors, AMD is losing revenue fast. And now that Intel is prepared to unveil its new 45 nm processors, while AMD continues to trail in the current 65 nm market, suffice it to say that AMD is in BIG trouble. They still have ATI, but I don't think that covers as much ground as they stand to lose from the processor market.
