Just installed an old 7800 GTX in my system to do some old school benchmarking. I installed the newest drivers and then loaded up 3Dmark 06. Scored a horrible 2600 points. opened up GPU-Z and noticed that it shows the video card only running @ 1X speed. I have a PCIE 16X board and all of my other video cards run @ 16X just not this one. Any ideas?
