I've decided to keep my Barton 2500 based system running a bit longer and need a new video card. I'm considering the X1650 Pro. Also considering a couple of nvidia based cards. My motherboard is an Abit NF7-S v2. A couple years ago...2004 maybe...I tried an ATI based card and my system wouldn't complete post. It's been fine with an fx5200 but I need a new card. Are there any common issues or problems with ATI cards on these? Anything to watch out for?
