BEST PCI-E CARD FOR ~$130:
Geforce 7600 GT
Codename: G73, 90 nanometer technology
12 PixelShaders, 5 VertexShaders, 12 TextureUnits, 8 RasterOperatorUnits
128-bit memory bus
560 Mhz core, 700 Mhz DDR (1400 Mhz Effective) Memory
The 7600 GT is an amazing card in this price range, sporting new SM 3.0 technology and very high clock speeds to deliver excellent performance. Its weakest feature is its 128-bit memory bus, but its high memory speeds offset that disadvantage and make it competitive with 256-bit cards like the X850 XT.
I will mention that ATI's new competitor for the 7600 GT may arrive in November: the X1650 XT. With 24 pixel shaders, it may have the power to compete with or even beat the 7600 GT in this price range, but it is as yet unreleased. Still, if you're purchasing in November, check if the X1650 XT is available yet and how its benchmarks compare to those of the 7600 GT.
