Geforce 7600 GS

Codename: G73, 90 nm technology
12 Pixel shaders, Five Vertex shaders, 12 Texture units, eight Raster operations processors
128 bit memory bus
400 MHz core, 400 MHz DDR (800 MHz Effective) Memory

With identical features compared to its faster 7600 GT brethren, the 7600 GS lacks only the core and memory clock speeds - however, the GTs clock speeds are so much higher, that the GS pales in comparison. Nevertheless, the 7600 GS is a great AGP card as it trumps the X1600 and 6600 GT for just a little more money, and is a good overclocker's choice due to the under clocked 7600 core - although it's unlikely its memory will ever clock anywhere near the 700 MHz (1400 MHz DDR) of the 7600 GT. Its only real competition for the money is the X800 GTO, which is a bit cheaper and probably a bit more powerful, but doesn't offer newer SM 3.0 technology or the ability to perform OpenEXR HDR.

Radeon X1650 PRO

Codename: R530, 90 nm technology
12 Pixel Shaders, five Vertex Shaders, four Texture Units, four Raster Operations Processors
128 bit memory bus (256 bit ring bus)
600 MHz core, 700 MHz DDR (1400 MHz effective) Memory

The new X1650 PRO is a re-dressed X1600 XT with slightly higher clock speeds. These clock speeds and efficient shaders help the X1650 PRO compare well against the 12-pipeline 7600 GS.

Best AGP Card For ~$175

Geforce 7600 GT

Codename: G73, 90 nm technology
12 Pixel shaders, Five Vertex shaders, 12 Texture units, eight Raster operations processors
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 X800 XT/X850 XT. The 7600 GT is the AGP user's savior, a decently priced card that can actually perform well for the money.
