Keep checking the vendor sites. I saw an XFX 8800GT in stock on Newegg yesterday (Monday) for about an hour and I passed (wanted EVGA). It then went out of stock.
I checked Mwave.com today and found 2 flavors of the EVGA 8800GT in stock. I quickly ordered the KO version for $279.99. By the end of my order, the price had jumped to $309.99 and they are still showing in stock.http://www.mwave.com/mwave/DeepSearch.hmx?scriteria=Video+Cards+eVGA+8800gt&All=y&DID=VID&PID=VGACARD-EVGA
Amazingly, I purchased the card and within half hour, MWave already had my tracking number and shipped it out at 8pm. I should be receiving it in 2 days!
