Hi everyone I have a Power Mac G5 1.8 GHz single core with 2 GB of RAM And a ATI radeon 800 XT graphics card. I'm running it on a 17 inch Apple LCD monitor and it is very slow and lags noticeably watching DVDs and In general. Even the screen saver. Running OS X 10.2.8 right now. Was wondering if you had and ideas? I zapped the P-RAM it helped a little.
