Well after 5.4 my wifes aging laptop has finally buckled so told her we are not putting it off any longer and I would build her a PC this week, I have part funded it to get her some extras and to be honest for a wow machine I think this will do just fine, also have the option of dropping in an i5 2500k when it starts to age and have only lost £50 on the cpu which if it lasts for 2 years is hardly a loss :P

Advice went both ways and advice I got from someone I trust on another forum who builds and sells gaming rigs including low end recommended that CPU as its not much off an I3 and is money saved, if / when that CPU becomes obsolete the £50 saved on the i3 can go towards an i5.
