Hello, I have a G5 7.3 2.0 dual core 3 gb of ram and ati 9650 video card. The machine is acting up a bit , the monitor will go fussy or suddenly shrink down to just a few pixels wide in the center of the screen. I believe the graphics card is at fault but I will be trying a clean install later to see if that could resolve anything. Any recommendations for a cheap replacement graphics card ? I looked on eBay & the card still runs for around $40 don't want to invest to much to keep this machine running. Thanks!
