Sept 10th is the day, we'll see if they are available next week either before or after that date. DRR2 in the HD4650 insures it will cost about $100. That is most likely a 256MM version and should be under $100. The HD4670 512MB DRR3 will go for around $120-125 and the top dog should be the HD4670 1GB DRR3 just about $150. People keep saying the HD4850 is cheap, I beg to different. Cheap for whom? Its a $170-190 card and yes many people think (including myself) that $200 for a graphics card is just too much, especially since I still roll with consoles for most of my gaming purposes.
Both cards will surrpass the HD3650 which isn't all that bad of a card, just not faster than the 8600GT. But ATI has responded with a card that's not only faster than the 8600GT, but 9400 and 9500GT and fairly close to 9600GT with no rebate making it an attractive option.
I will pick one of these up next week or whenever it becomes available
