Right, I think that buying an X1900 XT is a very good practical investment right now (for lack of choices if nothing else), but if you're somebody who wants to have a DX10 card as soon as there's a game that supports it, then you're going to be using a very expensive card just as a toy for the interim. Personally, I'm going to be buying a DX10 card next summer or later because firstoff, the prices will go down, secondly, there will be more Windows games actually supporting the damned thing, and thirdly, I want to use the GPU in my machine for more than half a year.
