I am not really into photo/video editing more in gaming like stuff like supreme commander
If thats the case then, if your going to overclock it is difficult not to recommend the E2180 for "bang-per-buck", otherwise it might be worth waiting until the price of the E8400 comes down to about £120. BTW the GA-P31-DS3L is a great budget OCing board, but as with all new intel chipsets only 1 IDE channel I'm affraid.
