RegHardware takes a look at Asus EN7600GT graphics card:

The 7600 uses half of the hardware that you find inside the GeForce 7900 GTX so you get 12 pixel pipelines, eight Raster Operations Units (ROPs), five pixel shaders, a 128-bit memory controller with support for up to 256MB of memory. The GPU comes in two versions: the GS has a core speed of 400MHz and 256MB of DDR 2 memory that runs at an effective 800MHz, and which is intended to be used with a passive cooler to give silent running. The performance option is the GeForce 7600 GT which has a 560MHz core and uses GDDR 3 memory with an effective speed of 1.4GHz, which is exactly what you'll find in the Asus EN7600GT.

You can play any game that you like with the 7600 GT, including F.E.A.R. and Half Life 2, and provided you don't want to run monstrous screen resolutions you can turn most of the eye candy on. So if you currently have a 6600 GT in your PC then we heartily recommend that you replace it with a 7600 GT immediately.

Nvidia intends that the 7600 GT should take on and comprehensively demolish the Radeon X1600, and for once it looks as though ATI is keen to play merely a defensive game itself in the mid-range market. It has tacitly acknowledged that the X1600 doesn't have a prayer. We don't expect to see the 80nm RV535 until August so in the meantime it has released the X1800 GTO. This is a cut-down version of the X1800 XL that has had the number of pixel pipelines reduced from 16 to 12 and a price of £170.
