I don't consider price after rebate to be retail price.
Like mdm-adph said, $95 is the cheapest on newegg.

Only PNY has one listed at $89 but the average is more like $110.
I consider putting $90 for the 9600GT in the review to be a little on the low side.
As a comparison, the cheapest 9600GT in Germany costs €80 (Palit) (PNY €94).
The Sapphire HD 4670 is already listed at €66 (that's $20 difference to 9600GT): http://www.alternate.de/html/product...l?artno=JBXSUG
The 9600GT doesn't have HDMI audio on chip. You need to connect the on board SPDIF connector to your soundcard the get sound over HDMI. ATI has this on chip. Not all soundcards have a 2pin SPDIF connector on the card, specially old ones. There is also the matter of encrypted audio! ATI includes the HDMI dongle, most of nVidia partners don't (+$5).
BTW $85 is the launch price for this non-reference model and it will drop over the next few weeks.
The 9600GT launched at $169 if i remember correctly.
