Looks like Nvidia is about to rebrand some products again. This time they'll be named the:
Geforce GTS 250 - 9800 GTX + - 9800 GTX
Geforce GTS 240 - 9800 GT - 8800 GT
Wow, 1 card three names.
The only change in this rebranding is that the GTX 250(9800 GTX+) will have an updated bios, and packaging change. None changes has been posted for the GTX 240(9800GT) as of yet. They will be announced on the first Tuesday of March; Cebit 2009.
I think this is a some not so great marketing strategy Nvidia has began to use, renaming/rebranding old cards with not much chance to make people think it's a whole new card. I think should spend this time and money of developing new chips rather than this.
