if you have a high end dx9 card... i.e. x1900 series, x1950series, 7900 series... you may want to hold on to your cards for a little longer, before jumping to the dx10 cards...(aside for the reason that there are no real DX10 games available yet in the market...) ati and nvidia are planning, or atleast rumored to be planning to release the next generation graphics cards... the R700 and the G100, 1st quarter of next year.
