I have the 9700pro, and it kicks ass.
As for a card to take on the GF4-4200, i would say a 9500 regular since the 9500pro can take on the 4600 and beat it.
Also ATI has been publishing drivers for the Radeon like there is no tommorow, and the drivers actually do something other then raise your 3Dmark
I love the card.
I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the darkness at Tan Hauser Gate. All those moments will be lost in time like tears in rain. Time to die.
