The 9800 is (very) slightly superior to the 9700 Pro, IMO. For the same price, the placebo effect of having "Smartshader 2.1" would lead me to the 9800.
As always, there's the tripe about "how long are you willing to wait, the new cards are just around the corner!!!!!" Just remember that the new ATi cards could be here in a month, sending the 9800s to the bargain bin.
"I've got a great new idea for a value product-line! We charge the customer the same price, and we give them a slower product!"
"How is that a value?"
"Oh, it's a value for us, of course."
