That's certainly a very good way to go, but for that money he could do...
And still be a good $70 cheaper. That can go towards the PSU i guess, and still have built a more powerful rig for less money. The APU system (while awesome and forward-looking) still won't outperform a 6 core Phenom in a 990fx mobo with a 750 ti discrete card.
If he wanted to minimize his investment, he could realize major performance gains with
And still have a machine no APU can touch, for under $300.00. In fact, that's a rig i'd be proud to own. Only thing i don't like is the 1.65 v on that memory. So for that money he could also get the SSD and PSU from your list, and basically have every single upgrade suggested in this thread, for under $450.00.
I didn't check the compatibility lists for these, don't just run out and buy them (although they should be perfectly sound builds, weird things happen and that's what the lists are for). My point is that as soon as you start considering replacing the entire rig, you put a big dent in the value proposition, to the point where (by discarding the most valuable parts of the existing system) you can end up spending more money to get an inferior machine, compared to patching something together.
I guess this might be the plan B for if there's no Microcenter around.
