Last I heard the GTX 295 is hitting around January 8th. That's straight up hearsay.
Bit-tech.net reported Jan 8th as the "earliest" date to look for it:
"However, because the card is not available on the market yet, and won’t be until January 8th at the earliest, the company has asked us to adhere to a number of restrictions."
Rollo over @ Anand is saying " rumored in 13 days" in a post he made on the 25th of this month.
"I also think the launch of the NVIDIA GTX295 is rumored to be 13 days away, and that it would be fairly risky to buy any multi GPU solution prior to that."
I've decided I'm definitely getting one for my Q6600|BX2 rig. It will be a nice upgrade for it, and a 3.51GHz quad is plenty of support.
