Advantages: Insanely efficient, SS4 instruction capabilities, unlocked multiplier
Disadvantages: fairly expensive, some more programs need to be multi threaded

...were looking very dire for Intel indeed. Massive job cuts, poor PR and above all they had an outdated series. Their main rivals AMD were trouncing them at every step. They left no stone unturned and Intel seemed to be in major trouble. Then the Conroes hit the market. Instantly the tables were turned. The new 65nm process Intel adopted, dominated the market. They ran cool, extremely efficiently and above all they overclocked. Fast forward to today ...
...overclocks even better than before. Intel knows what consumers want. Value for money. On my meagre rig ;) I managed to overclock the QX6950 to over 4.3Ghz on watercooling. Unfortunatly my motherboard cannot go anyhigher so for the time being im limited. However being the Extreme version, this chip allows you to drop the multiplier to negate the limitations of the other components. Would I recommend this chip though? Maybe. As much as I have raved ... Read review

Advantages: Unlocked multiplier
Disadvantages: Price, same performance can be had with overclocked Q6600/6700 for less

...Back in the older days, Intel used to differentiate the Extreme editions from the standard Pentium 4's/D's with more cache or Hyperthreading. Since the Core 2 Extreme Editions have been released, the only aspect these have that can't be found on the standard Core 2 Duo's/Quads is an unlocked multiplier. Sadly that's the only feature and is it worth 2x the price, I think not!. a Q6600 G0 or even B3 can be overclocked way beyond 3GHz using a 8x or ... Read review

Advantages: Blistering speeds
Disadvantages: Ideally needs Vista 64 bit but few software compatibility probems

Intel have really got it right with this CPU. It was easy to install and runs like a dream. To take real advantage of the power of this CPU it really needs the Vista 64bit version and there are few software compatibility problems now so it is worth taking the plunge. I've never seen software install so quickly on a PC as with this processor and running Windows updates, background tasks, processor hungry games etc. just doesn't have an impact on the ...

Advantages: Price, performance
Disadvantages: Heat

A brilliant processor, can run the latest games with ease. Brilliant value too! I play the likes of crysis and cod4 seamlessly with this processor. There are a few things you must be careful of though, first of all this processor gives out a fair amount of heat! I dont feel that the supplied fan is good enough, but that could just be because of my cramped case. Secondly, the edges are sharp! I cut myself while installing it. Be careful! This is ...
...it didnt complain at all. Thats with an aftermarket cooler though. I upgraded from a single core and was surprised the massive difference it made. So, in conclusion, this is a very impressive cpu for an appealing price! Just look at the ciao price comparison and you will see it available for £75! a bargain. I bought mine at £100. I wish i had found ciao then! ... Read review

Advantages: great for office use. endures high temperatures. has average life of 5-10 years
Disadvantages: can not be used for gaming purpose. Windows Vista might not work

This is an absolute great processor for office use. It can bear very high temperatures, and with the right motherboard and bios it can be overclocked easily. Works great at Windows XP when using word, internet, reading your e-mail etc. (office use). When this processor is installed properly and doen't have to endure very high temperatures it will have probably a lifetime of 5-10 years (maybe even longer). I used it for about 7 years and never got ... Read review
