Why is what better?
And also, the fact tah the card can support dx10 doesnt mean it can perform better. It just means taht it can play a wider variety of games (like consoles ina way). The thing is that dx10 games are not out yet, so really, RIGHT NOW, dx10 cards don't benefit anymore than a dx9 card. Also, since dx10 games arent out yet, its hard to say how well the dx10 cards will even perform on dx10 games WHEN they come out.
(although there are quite a few indie dx10 games out already. someone, somewhere has probably tested how well dx10 cards run using those applications, even though they aren't official retail games...)[/QUOTE
i was asking why is the 8600 $50 better than the 8500
