I'm thinking of getting a 512mb ATI x1900 xtx, or perhaps a x1950xtx soon. I've seen info on those nice Nvidia 8 series, but I just know you can't get them for under $400 CAN. I just want to know if it is worth getting a direct x 9 card at this moment, or to wait for the direct x 10 cards to cheapen. Will the x1900/1950 work just as well with direct x 10 and use it to its potential(excluding the fact that they have lower specs than the Geforce 8s)?
