Kinda about this situation, I've got a Dual 2 Ghz G5 with 10.5.8 loaded on it, yet I'm getting very slow flash performance. The PC that I'm typing on is a $300 Toshiba with a celeron processor but it does a great job with flash (safari/firefox/IE across the board). Is there a remedy for this? I googled one tip that said to disable hardware acceleration, but it didn't make a difference. When I opened up the Activity Monitor, processor usage was up to 100-150%, so something is not right, the G5 should chew through this.
