I agree he should switch over to intel at this point in time. Im an AMD fanboy, my 3200+ is a beast compared to its intel counterparts, crysis and cod4 work great. But in the current market Intel's chips have the edge at the moment. Very possible the coin could flop sides again at any time as every company makes good and not so good products.
I've just started ordering parts for my new rig and it pains me to buy an intel product, but as someone that can only do a full overhaul every 5ish years intel is just the way better option to get my moneys worth.
Just my two cents on that, if AMD is the choice though I would recommend what you stated about getting a good mid-high x2 series chip and then moving on to the phenom(sp?) once they get a couple generations of chips in.
