what is the best option

[rickie22]

which is best?

intel P4 3.0GHz LGA775 800fsb.

or

intel P4 640 3.2GHz 800fsb.

Buying a new computer for roughly £700 and I am a bit bamboozaled by the options. Any help would be great.

Well nothing really, about .2 of a Ghz and price?

Sorry not being sarcastic ... but Intel are not my forte


Now, not wishing to throw a cat in there ... have you had a look at AMD?
Cheaper, faster ... more understandable ...

The P4 640, does have the extra 0.2GHz, but also has EM64T (Extended Memory 64 Technology), which offers a degree of 64-bit compatability, whereas the ordinary P4 3.0 is only 32-bit.
The P4 640 also has "Execute Disable Bit", which is a clever little buffer overflow protection against some malicious code and worms etc.

I would choose the 640, but you will need a EM64T compatible motherboard too, and will also need a 64-bit Operating System to take full advantage of 64-bit capability.
