In response to ATI releasing the X1800 XT, Nvidia has announced that they will start collaborate with OcUK to launch the 512MB GeForce 7800 GTX on November 7th.
“On November 7th OcUK will be launch partner with NVIDIA on the new faster clocked 512MB 7800 GTX which will further establish NVIDIA as performance leader and OcUK will have priority allocation on 512MB cards which could also mean we have exclusivity, and unlike ATI, NVIDIA will be shipping plenty of stock throughout November.”
