Cheap Intel CPU

I have just started building systems for a small profit for friends and i currently have a request for a £500 pc that can game reasonably. it will be running a 22" screen (included in £500) and i will most likely be using an ATI 4670 GPU however i need an intel processor that will keep up with it and not waste the performance. how fast a processor do i need (open to minor overclocking) currently looking at a intel e2200 or e2220 £50 and £60 respectively stock or with a small OC are these ok

Thanks
Tom

oh yeah forgot to mention will be using asus p5v-vmsedh board as have got one of a friend new for very good price so wont be changing. i have heard e2160s oc well what kind of performace could i get out of them on that board

Get the E5200, its %52.64 on dabs and its way better than the e2x00, its 45nm and will easierly OC to just over 3ghz on stock voltage and coolers

specs of board here only 65nm unfortunately would not use if wasn't for the fact i just have it

Agreed, it is better, but unfortunately the board only supports 65nm. There may be some kind of bios update, but I can't find it.

I would think once it gets to around 2.4 at that resolution the graphics card will limit it more than the CPU
