I managed to obtain a 7900 GT from a company called Antares Digital
in New Jersey. Ordered it yesterday (Thursday). I tried every reputable vendor I could find, and there were no 7800 GT's or 7900 GT's in stock. These guys only had two reviews on reseller ratings (both positive), but I had a good gut feeling about them, so I went with it.
They responded not too much later with a confirmation note that looked like it was written by a human, and informed me that they'll have it shipped out later the same day. Sure enough, a couple hours later, I got my tracking number in another non-form-resembling letter. And by virtue of them being only one state away, I had this huge box in my hands this (Friday) afternoon!
Now if only my motherboard order from Newegg wasn't stuck in a UPS warehouse in Philly...

This graphics card comes in the biggest box I've ever seen. It has a plastic handle on the top! The actual card takes up probably 1/7 or 1/8 of the area when you open it.
