I bought a used X1900XT 512MB instead of the X1950XT 256MB, check the FS/FT forum . So far, I am very pleased
and saved a little money. If you are sticking with XP and DX9 for a while longer, then the X1900XT and X1950XTs are
great choices. Yes, the 8800 GTS is all around faster, but the performance increase was not worth the price difference
to me. 512MB might not make a huge difference now, but it might make just enough difference once the DX9/DX10
crossover titles come out. If I was running exclusively at 1920x1200 or higher, then the 8800 might be worth the
investment, but the X1900XTs can manage fine with the right balance of PQ settings.
