Another option, although less expandable, is to look at an FM2. It performs less per core but there are 4 of them and better integrated for the same price as the 3225 (6800K + FM2A75 Pro4), which, by the way, if you're going to use integrated well, the 3225 has the same as the i5 K and the i7 3000 series.
It is true that building an AMD platform today in the mid-range or low-end has some very cool things, but since for him the priority is that it lasts a long time, coming from an AMD 2600 + well, for that reason, in a few years he could get a micro like the 2500K that with overclocking we all know how it performs. In fact, you can find 2500K for under 150€ second-hand, and despite having some time behind it, it's a great micro.
While it is true that if he doesn't want any trouble, a current AMD 4-core, without reaching the level of Intel, is more than decent. I would love to have one of those ;D so he can decide if in the future he will change micro, or if he wants a powerful micro from the start, although it doesn't reach the level of the 4-core Intels.
Here you can see a bit how the AMDs of various sockets perform, see if the AMD platform interests you: AMD A10 6800K review - Game performance GeForce GTX 580 - Far Cry 2 | Battlefield BC2
