HotHardware has a review of the X1950 GT 256MB.  By dropping the Pro part of the name, reducing the clock speed and the price, this card is good choice for those not looking for the fastest card.  It’s performance is still nothing to sneer at, it is capable of over 100fps with 4x FSAA and 4x anisotropic filtering enabled in Half Life Episode One.
‘Sapphire clocks the Radeon X1950 GT at levels which are close to, but slightly lower than the Radeon X1950 Pro. While the Radeon X1950 Pro featured the RV570 GPU clocked at 580MHz with 1.4GHz GDDR-3 memory, the Radeon X1950 GT features the RV570 at 500MHz with 1.2GHz GDDR-3 memory. While a 500MHz GPU clock may seem quite high for a mid-range part, keep in mind that this GPU features 36 pixel shaders, which is 3/4 that of the high-end Radeon X1950 XTX.’
