Advantages: Fast, quad core, cool running, guranteed G0 stepping
Disadvantages: Q6600 can be had for half the price for only 266MHz less performance

...can confirm this using the Intel Processor Identification tool on their website. G0 means it runs cooler than the older B3 stepping but also is bound to overclock more. The bad news is that i's 2x the price of a Q6600 for only 266MHz more performance. As long as you can get yourself a G0 stepping Q6600 there doesn't seem a point in spending double on this Q6700, unless you want the 10x multiplier for something. Anyone who does video/audio editing, ...
...extra cores will profoundly be delighted with this CPU. It makes such a more sensible buy than going dual core. Games and program that don't take advantage of all cores will steal yield a snappier system as the Operating System can spread the load more evenly so you can play a game + encode a video all at the same time without it impacting performance. Boxed versions come with a 3 year warranty, OEM versions come with whatever the merchant offers, ... Read review

Advantages: Fast clock speed / Good amount of lvl2 cache
Disadvantages: Could balance out workload onto both cores a bit more

...may know this is an Intel Core 2 Duo E6750 / 2.66ghz cpu, It has 2 cores on the one chip. it runs with 64-bit architecture which then opens up a whole new world of 64-bit operating systems for tommorows technolodgy...this along with the fact it has 4mb lvl2 cache makes superfast repsonse rates to programs and files i have also noticed that their are not so many "cache misses" to which i expected so this pleases me the most :D The only downside is ...

Advantages: Blistering Speed
Disadvantages: None

...is the 2nd generation (already) Intel processor based on it's 'core' microarchitecture. The previous being called Netburst, and is still around in Pentium 4's and Pentium D 9 series processors. The beauty of the Core 2 Duo chips are the incredible power they are capable of, which producing half the heat of the Pentium 4's. On benchmarking, this processor alone increased the speed of my computer by 53%. This is a huge amount considering i payed less ...
...The processor has a very fast Front Side Bus (FSB) speed of 1066 Mhz and will work with the fastest Ram you can throw at it. It also stays very cool, even under excrutiatingly hardcore tasks, like encoding 3 DVD's simultaneously while editing my photos in the number crunching monster that is Adobe Photoshop CS2. The brilliance behind it is due to several important things. There is a 4Mb cache (which is a lot more than AMD give you) which is shared ... Read review

Advantages: Extreme performance, very stable, low power consumption
Disadvantages: High price, in future I recommend 4 cores (distant future)

...of shared L2 cache , Intel really did a great thing for the consumers. The prices is still high but for those who can afford it is really the best dual core processor. Performance. The performance is best in all domains:games, multimedia, encoding, only loses in quad core specific applications and are few of them. Ease of Installation. Based on the socket 775, the installation is not very difficult but take care that the cooler's 4 conectors to ... Read review

Advantages: Good clock speed, good video decoding and overall reliabilty
Disadvantages: Only 2 MB cache

The Core 2 Duo e6400 has many good features: It uses a 1066 MHZ FSB (front side bus) for a fast link on the motherboard. It 2 cores running at 2.13 GHZ The Processor is very EASY to overclock; just be careful. It is energy effecient and runs cool, unless you over clock Not as good features: 2 MB cache low compared to others in the range I found this processor to be excellent; it was extremely fast. With this processor there is no worry of ... Read review
