Advantages: 4 cores. New G0 stepping Q6600 runs cooler and is easy to overclock
Disadvantages: Software doesn't take advantage of all 4 cores.

I bought this a while ago for £160 even at that price it is a bargain and now you can get it £140 a no brainer in my opinion. An extremely powerful processor 2.4Ghz per core adding up to a total of 9.6Ghz. The best thing about this processor for me though is its potential for overclocking, if you get the new G0 stepping which is a must this processor can easily be overclocked to 3.3Ghz just by using a good cooler such as a Scythe Infinity and would ...
...default cooler. This processor will do it all if you want to encode a video no problem I have encoded a full 90minute film in less than 30minutes and while I was doing that I was also playing a top end game without any lag. Coupled with 2Gb of fast DDR2 memory and a good graphics card such as a 8800GTX your new rig will easily be able run new games and future games for many a year. The easy installation of the LGA775 socket makes it a breeze to ... Read review

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 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, 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
