Asus GTX 470+ Free Shipping & a free Asus DVD Burner for $350 sounds like a decent deal to me!
You might also consider that NewEgg had an eVGA GTX 470 + OCZ 600W or 700W PSU for $350 after rebates as well. I posted a thread here in the Graphics section about it last night. If you're in need of a PSU that may not be a bad deal.
The pop out cooling fan on that GTX 470 bothers me though. Could cause problems if you ever wanted to SLI. Not sure what the point in that thing is. Although the cooling fins under it would probably cool better than the stock unit (is my guess).
One appears to be factory OC'd whereas the other provides you with the tools for a factory OC. WOuld have to find both tested in same rig using same tools to make a fair comparison. I think the free DVD writer would force my hand to the Asus Model.
The Galaxy article reports a core clock of 625 and 837 on memory and 1250 on the shader...the Asus article they went up to 778/901/1555
An 850 watter would handle two of them (perhaps not at the extreme OC that they used in the Asus article) which leaves you room for adding a 2nd card later:
