Soo um should I just wait for dx10 low price cards?

[Xarick]

my 9800pro is not running new stuff so of course I was either gonna buy a 7900gt or a x1950 pro. But the more I read about dx10 the more I wonder if I should wait until the $200 dx10 cards come out. Cause I am not gonna be able to do another upgrade for about 2 years.
