Images have recently surfaced that pretty well conclusively confirm the specifications of Nvidia's upcoming GeForce 9800GTX graphics card.
The card which was exposed is called EN9800GTX and it features all the usual goodies - PCI Express 2.0, DirectX 10.0 (still not DX10.1) and OpenGL 2.0 support, 512MB of GDDR3 memory and triple-SLI. This specific card is based on the reference model from Nvidia which mean it carries default clock speeds. In Typical ASUS fashion, they will probably launch a factory overclocked "TOP" model sometime after the launch (April 1st).
At least on paper, it looks like nothing more than an overclocked G92 8800GT 512MB. The price tag is expected to be around $350 USD which is a reasonable price but if you were expecting a new card with ultra high performance improvements, it doesn't seem like that will be the case at this stage and from what we have seen and heard so far.
As you would expect, we have 9800GTX samples already on the way and testing will begin very soon!
