The long awaited green response to ATI’s mighty R580 core has finally surfaced with the launch of Nvidia’s G71 (NV47) core.

As with its predecessor the 7800, the 7900 comes in two flavours - the high end GTX and the mainstream GT. Both have been designed for Extreme High Definition Gaming (XHD) on widescreens up to a resolution of 2,560 x 1,600 with high image quality settings while maintaining high frame rates.

Each card will also have dual dual-link DVI connections.

While the 7900GTX has the dual slot heatpipe and heatsink cooling solution last seen on the 512MB 7800GTX, the 7900GT has a neat single slot solution with only the core being cooled, the memory chips are left bare.

You can read the full review of the 7900GT and we'll be posting our thoughts on the 7600GT in a short while.
