Having just bought a 23" ACD for my Mac, I was also wanting to run it on my old PC that I still use for games (currently has Radeon 9700 Pro graphics card). I thought from checking the specs beforehand that the Radeon 9700 would work with the ACD, but it doesn't - I just get a load of multicoloured vertical lines rather than a display. So, I'm looking for a recommendation for a new card: AGP interface, preferably sub-$200 (£100), reasonable 3d performance (comparable or better than my current card), will work with the 23" ACD. Help me, MacRumors hive mind! p.s. I have searched (here and with Google), couldn't find anything!
