There isn't much worth noting from $667, really. The R9 280 x is the only interesting bit, though I guess you could probably just overclock this 280 model to get there.
Even at a low price, that's still a steal for an E7200 plus the motherboard and cooler.
You could probably go with $83.
EDIT: $50 processors from what I can tell, maybe put in at least $67. If you don't need the cash right this second, you might have to start a bit higher.
The GTX 440 is actually a decent deal, but everything else is just a disaster. I wouldn't touch any of those other options if I were you. If this hasn't sold yet, maybe grab it:
Not really, I’m running 4GB so I can actually have two games open at once along with Chrome, Skype, and a few other things running in the background—I hit 3.5GB once before.
Btw, it might run a little slower (though hopefully you won't notice) if there's too much free RAM.
If he grabs that one, it's identical to yours and should pair perfectly with his processor. Honestly, though, you can find GTX 750 Ti cards for barely $333, so $433 seems way overpriced to me. If he isn't set on buying from Links, maybe check this out:
One little plus is that both cards have really low power draw, so he probably won't even need to swap out his power supply if his current one is a bit of a junker.
Unless your motherboard is total junk, I’d suggest grabbing an LC-CC-95 cooler pretty soon if you want to try some overclocking. It might actually help those Athlon chips quite a bit... you could probably hit 3.3GHz without even touching the voltage, I guess.
He probably needs to watch his distance from the screen, too—it really should be at least twice the width of the monitor. Though, I guess if he doesn't mind a larger setup, he could always go bigger 😉

No optical drive, the case doesn't have fans included (though you could add some), an entry-level motherboard that gets the job done, a small hard drive, and just 4GB of RAM. I guess the CPU and GPU combo is probably the strongest part here and should deliver decent gaming performance, but otherwise, the build feels a little unbalanced.
This looks like a perfect fit for your rig. It pulls a bit more power—since your current power supply isn't exactly top-tier—but it should be just right for your processor, I guess.
