ATI's X1950XTX is supposed to be retailing for $449 as a MSRP. It is currently available at Newegg.com for $419, not a bad price for what you get. Performance in the high-end today is sufficient for high resolution gaming with anti-aliasing and anisotropic filtering enabled and the X1950XTX delivers performance in spades, beating other single card solutions out there by a nice margin. The performance difference between the X1950XTX and a X1900XTX is apparent especially at high resolution.
ATI was late to the party with Shader Model 3.0 hardware like the X1800 and X1900 series, with internal delays and problems with performance of early parts meaning the X1800XT did not reach store shelves until October of 2005. The X1950XTX is exactly the same card as the X1900XTX with GDDR4 memory and a better more silent cooler. It is the only game in town to play games like Oblivion with HDR and MSAA enabled at the same time.
