4300 vs 4400

Not being familiar with the Core2Duo range, I was wondering if the £15 price difference between the 2 chips was worth paying for the extra performance, considering that I'm not averse to overclocking, provided it's easy and failsafe.

On another note, is the 6320 worth the extra £15 again on top of the 4400, if the PC is to be used for general internet/e-mail/occasional gaming.

I will probably be adding a P5B basic and 2gb of TwinX Corsair memory at 4-4-4-12, whatever that means.

I've just been through that. Went with the E4300. You save enough over the 6320 to risk serious overclocking. General consensus is the 4300 is good enough, and I wouldn't have thought the extra 200mhz makes that much difference.
