CPU comparison for mid range

Hey, im new here, i no a decent amount about computers, but im probably a bit of a noob here...

anyway, im thinkin bout buyin a new system, and one of my biggest problems is knowing how the different AMD and INTEL processors stak up to each other. specifically im interested in mid range dual core processsors, bout 2.5-3 Ghz per core.
wat would an equivalent for the INTEL E8400 dual 3.0ghz be? and also for the AMD dual 6000+? and how good a processor do i need in a mid range system, costing about £700, (thats including OS, MS office, 19" screen)?

Link to the site where you will be buying. Give us a list of all the hardware you will be purchasing. Folks will be happy to give you some ideas on your best 'bang for the pound' ...

And then argue with each other about it

edit: I fergit. Open Office is free and (unless you are a super-duper MS Office power user) works like a charm ...

i will recommend the 6000+, there was another price drop today so its only $93 on newegg. thats actually an astonishing deal when paired with a 780G MB.

actually, better way of working this out. i wanna spend bout £600-700, an i also wanna CPU, graphics card an RAM that are all matched, eg, i don want one bit bein amazing, but being bottle necked by another poor component

ATM im lookin at cube247.co.uk, they've got some very good deals, though they don say wat mobo an PSU they gt, might hav 2 ring em to find out
