The 650 MHz core / 1625 MHz shader lines up with a GeForce 8800 GTS, but it has too much memory (the 8800 should be 512 MB) running too slowly (900 MHz instead of 970 MHz) and the wrong bus width (384-bit instead of 256-bit). It could also be an overclocked 8800 GT (stock 600 MHz core / 1500 MHz shader / 900 MHz memory) which also came out in a 1 GB version, but even then the bus is too larger and PCB also seems too short for an 8800 GT?

Here's the card be bought:



From the from of a graphics card (by the DVI/VGA connectors) to the back of the PCIe connector is about 258 mm, so the above card is about 314 mm long. The 8800 GT seems to be about 328 mm long.

It could be an overclocked 8800 GTX (stock 575 MHz core / 1350 MHz shaders / 900 MHz memory) but the memory size is wrong.
