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.

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 ...
