hi there, i bought a 7900gtx 512MB - 40EUR. further i flashed the card with a rom biosfile from the nvidia fx 5500 quadro card (these card have the same core). now i have a nice quadro-card to work with my CAD programs. i tried to flash an 7800gtx 256MB to an fx 4500 that dont work, maybe the the 4500 has 512MB ram and so the bios ist not compatible. But you can softmod it with rivatuner! in my pc is now the flashed fx 5500 and a 9600gt. under winXX i work with the 5500 and wenn i play a hard 3D game i disable the 5500 in the devicemanager reboot and switch the monitor on the 9600gt - and play the game! thats all
