Sorry to here about your problem. I also run dual monitors, but with CRTs and an ATI 9000 pro.
I have heard of people having problems with ATI cards though. I think I know your problem though. Your new monitor needs a good card, especially cause you have two. I suggest that you go with a Radeon 9800 pro, like you said. This will push your pixels just fine and should solve the problem. The thing is that 10.3.8 runs more performance from your card and the cards you have tried I am guessing can't handle such a large LCD and a large CRT. Go for it, you can get the resolution and stability you need. Props to dual monitors-read my up coming article to them! :cheer:
