If you can afford to spend $150, the Radeon X1950 GT is pretty hard to beat at that price point for S.TA.L.K.E.R. The X1950 GT isn’t quite as fast as its predecessor, the X1900 GT, but as we discussed in our Sapphire X1950 GT review, these cards are based on the exact same GPU used in the X1950 Pro, so it’s not hard to get more performance out of these chips with a little bit of overclocking. In the US Sapphire is the only board partner bringing the X1950 GT to market at this point, while in Europe and Asia Palit and TUL are the sole card manufacturers. NVIDIA’s GeForce 7900 GS also performs well, but at stock speeds it isn’t quite as fast as the Radeon X1950 GT. A factory overclocked 7900 GS card would no doubt fare better in S.TA.L.K.E.R.
