ATI will launch its new graphics card lineup next week and NVIDIA is said to be planning a GeForce 7800 GTW with 512MB memory as ATI will offer 512MB memory versions of its Radeon X1800 XT and LE.
Nvidia believes in availability and wants to send press samples shortly before the card is available but we suspect that this might happen shortly. It needs to make a new PCB in order to accommodate more memory chips and we don’t think that Nvidia will play with the card's clock. We are quite sure that GTX remains working at the original 430MHz core but there is some space for Nvidia to overclock the memory. We still don’t know whether that will take place or not.
