Disadvantages: Not suitable for beginners

I had an old Pentium 100mhz CPU computer, which I inherited,and it seemed a tad slow (for good reason!).I had seen this upgrade available at various mail-order firms and saw that it was available for socket 7 motherboards,at Pentium 75mhz upwards.

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.

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
