More info is detailed around the web on the GTS 250 release next week of course. But it's pretty safe to say that the card will use the 55 nm G92b graphics core and is as rumored specs wise similar to the GeForce 9800 GTX+

There are some interesting features though ...  The GeForce GTS 250 will come in 512 MB and 1 GB configurations, partners will be free to use their own designs as well. Rumor has it that some partners even seem to be working on 2 GB models, which can be discussed of course. Since the card is based on 9800 GTX+ the card is equipped with 128 stream processors. The 9 inch long PCB and cooler visually bear a striking resemblance with the GeForce 8800 GTS 512MB for sure. Also a change, a single 6-pin PCI-E power input is enough to feed the card. The GTS 250 graphics cards are NVIDIA's 'new' card series to address the 125-175 USD market.

NVIDIA will lift the embargo on this card on March 3, the cards will reach retail and etail by March 10.
