I've been searching a lot recently to find out what Nvidia's plan is for releasing new cards. I'm interested in upgrading but I don't want to right now if there is some new ones coming out. Is there any plans to release like a card that has a 512 vram and 256 bit? More less filling in the gap between the 8600 GTS and 8800 GTS. I've heard there maybe would be a 8700 GT or a 8900GT to have this.
