Advantages: Fairly cheap
Disadvantages: Low cache, Tends to start running poorly after a while

The Celeron 2.8GHz is a fairly cheap processor, but cheap things come with disadvantages. It tends to run nice and cool at about 30C-35C most the time but during long (or sometimes short) gaming sessions things start to slow down and causes a huge hit in FPS, which can be seen going from 60fps to 10fps or less due to the cache being so small and the simple fact that the processor is a Celeron (cut down version of a Pentium) I would advise people ...
...your using this for gaming, unless your only doing things such as 2d work, emailing, web browsing then this processor is more than adequate for that kind of work. Be warned: if you are using a socket LGA 755 youll have a nightmare trying to install the heatsink for this thing, once you get two clips on its next to impossible to get the third or fourth clamped down. ...

...XP SP2. I like this AMD processor because have dual core system and more faster than Intel Pentium Core Duo 2.2Ghz.

Advantages: fairly good price, dual core, 2.66 ghz, 4m L2 cache
Disadvantages: fan is somewhat hard to install

This E6750 is the processor running in my computer as I write this review. In my opinion I couldn't have chosen a better CPU for what I was looking for. I was looking to spend around 200 USD for a processor and I wanted it to be very powerful so that I could run demanding programs and all of the most recent games. This processor combined with my 8800 gts 320md graphics card put on a show when it comes to graphics displays. I have yet to be disappointed ... Read review

Advantages: Quite Fast, Overclockable, Cheap
Disadvantages: 1mb cache

I have had this processor in my PC for around 7 months and it is probably the best value processor around. I put it i my first ever build and it was very easy to install and very fast,probably the fastest PC I had ever used! After a few days I messed aroung with overclocking and this is when I really unlocked its potential. I don't really have a clue about memory timings etc. so anything extra I could get out of it the better. I could get it up ...
...but its now sitting at 3Ghz as it has been for 7 months and it flies! I have played quite a few games with it including COD4, PES 2008, FIFA 08, GTA SA, Half Life 2 and more, very smoothly. I can also convert a 2hr film to DVD in around 50 mins, on my old computer it would take 4hrs. Overall a cheap and Cheerful processor ... Read review
