There may or may not be a benefit to this at this point. Basically what you are doing is taking away the CAD Rendering/OpenGL functions from the GPU and turning it into a gaming card. Its my opinion that the Quadro cards should be flashed with the Quadro BIOS - i.e. flash your 1500M with the 2500M BIOS. Thats all the GS guys are doing to get a GSX. So I personally believe that the 2500M BIOS would give you similar results to what our GSX mod is giving us, with the added benefit of keeping the CAD functions intact. Keep in mind that its not the GPU itself that makes a Quadro a Quadro. Its the surrounding architecture of the board that supplements the core and makes it optimized for OpenGL. By flashing the BIOS to that of a GTX you are simply subtracting those additional functions. So, try the 2500M BIOS first and see what kind of clocks it will allow you to hit. Then try the GTX BIOS and see if you can really get higher clocks and scores.
