Advantages: Very Fast, Stock fan is not too loud
Disadvantages: Further overclocking would require a better fan

This is the fastest standard Intel Core 2 Duo you can buy, the E6850 has a 333Mhz FSB which is 1,333Mhz Effective so it has more memory bandwidth than its descendants. The E6850 has a VID of 1.35V most of the time (some of them have a VID of 1.3v although it's uncommon) and runs slightly hotter than a E6750 with a VID of 1.3, during my tests I also noticed it is harder to overclock than an E6750 but only by a small amount, me getting the clock speeds ...
...get the E6750 up to just under 3.65Ghz, this was just with the boxed fans that came with the processors, although if you bought custom coolers, you would get much better. Conclusion: While I could not get it to overclock as high as an E6750 in my tests, you could easily reach over 4Ghz if you bought good enough cooling for it, however if overclocking is not for you, this processor is still an ace to pick up and will run any of tomorrows software ...

Advantages: Very quick, highly overclockable.
Disadvantages: None, except there are not many stock often.

...any problems or voltage changes. Intel recommends a voltage of 1.225 volts. When compared to the Q6600 this processor might fall behind but at the moment hardly any problems utilize all 4 cores and the the moment 2 cores is enough. However if you are willing to spend another £20 -£30, i would recommend but the q6600 because in the future programs will take advantage of the four cores. The heat sink provided in the box is better than i expected, it ... Read review

Advantages: Very fast, cheap
Disadvantages: need to have IT expereince

This intel dual core processor with 2.33Ghz speed (total speed of 4.6Ghz) with a 4MB Cache can handle an awful lot of demanding programs runnning at once, obviously it has its limits, but for the price its a very good processor. This processor is also compatable with 64 bit computing. It has an LGA775 Socket which is compatable with most of the new motherboards if you are looking to upgrade or build your own pc. If you are looking to buy a processor ... Read review

Advantages: Fast, energy efficiant, cheap
Disadvantages: intel have announced 6 core cpus on the way

Excellent Processor, the usual simple to install and the stock fan does its job well. Very overclockable and can easily reach speeds of 3.0ghz without having to change the cooler. In my oppinion certainly worth picking up as great value for money also with the release and rapid take up of quad core cpus the price of these dual core processors is only going to carry on going lower, meaning if you dont have a need for 4 cores pumping out your office ...
...graphics work that need the extra cores, grab one of these. They will amaze you at the performance you will receive especially if upgrading from something a lot lower, i personally upgraded from a lowly AMD Athlon 2600 and was happier than a sandboy in a jam packed pub. ... Read review
