If you abselutly cant wait than gor for the x1950 pro or xt. If you can wait then wait for next gen mid-range cards. 8600Ultra with 64 unified shaders, 256bit 512mb ddr3. or get the r600 mid-range card which no-one has any idea about. It's all about the waiting game. your choice.
1950xt all the way, they run about $250. Although if your willing to wait for the midrange dx10 cards to come out something like a 1950pro would be a good place holder.
