According to the Sparkle, it will be releasing this 8800GT card with (as the name implies) 1GB of DDR3 memory and the passive cooling system known as Cool Pipe 3. They didn’t cut on the clocks you'll note. The passively-cooled 8800GT will maintain the 600MHz core clock / 1.8GHz DDR3 / 1.5GHz shader spec from Nvidia, much to the joy of gamers everywhere. Sparkle also claims that this 1GB beast is backward compatible with “the original PCI Express standard”. We haven’t seen anyone actually sticking a G92 card in a PCIe 1.0 or 1.1 slot, but it makes for an appealing selling point for upgraders.
