I just picked up another G5 for a damn good price and it had a flashed 9800 pro PC card in there from what it looks like. Got a bunch of lines everywhere so I just got done flashing just about every Mac rom I could find and those lines are not going away. Nope. Oh well at least I got a complete G5 with 2 large hdds and 1.5 gb ram and dual 1.8ghz and 8! memory slots for probably less then what most people pay for just the Mac 9800 Pro's . Would using a better thermal paste do better? The lines look like they are from over heating? I've also tried downclocking the card but that doesn't do anything either Guess it was just a bad card to begin with as I've flashed plenty of 9800s on a G4. Pretty cool to finally do it on a G5 with 10.5, didn't even need to boot to safe mood like when I had to on the G4s. I do have 2 other AGP cards from G4s MDDs but I'm not sure if they work or not since I don't have a DVI cable, anyone know if a ATI 9000 64mb card or Geforce4 64mb cards work in a G5? Thanks.
