Word is circulating that just four short months after the launch of GeForce 9800 GTX and GeForce 9800 GX2, NVIDIA will welcome its new high-end graphics cards to the world. Logically their names will be GeForce 9900 GTX and 9900 GX2. Both cards will be based on the GT200 GPU. Details are all you want I'd say, but unfortunately there's not much to know. According to VR-Zone, GeForce 9900 GTX is to replace 9800 GX2 and this gives us a clue that a single GT200 card will actually outperform a dual G92 card. The story also suggests that the GT200 will still be manufactured by the old 65nm process, and the PCB used for the new cards will probably be P651. The release date for both cards is also said to be in July. I know this comes just a day before April Fools' Day, but the report has been posted all over the web, so we can assume it's fairly legit.

I'm really surprised that its so soon and already new plans are out.
I'm also not even sure if there's any game out there (except Crysis) that will even need all this much power!
