>> NVIDIA GeForce GTS 250 technology preview
The real news surrounding today's launch is the introduction of a 1GB variant of the GeForce GTS 250, positioned at the same $149 US price point as the original 512MB GeForce 9800 GTX+. This additional 512MB of frame buffer space isn't the only difference to be seen on this board however - The 1GB GeForce GTS 250 also gets a new, smaller PCB, reducing its size from the 10.5 inches of the GeForce 9800 GTX+ down to just 9 inches, thus causing less potential space issues for both consumers and system builders. The power requirements of this board has also been tweaked, leaving this new part requiring only a single six-pin PCI Express power connector rather than the two six-pin connectors currently needed by the GeForce 9800 GTX+.
