Hey guys, I'm a long time lurker, super-seldom poster. But ya helped me out last time, so i figured I'd try it again. I installed Tiger today upgrading from Panther. I noticed when I would start up World of Warcraft, Warcraft 3, or drop new widgets into use my video card lets out a high pitched whine. It seems doing any intense video effects taxes the card. with the widgets the whine stops when the effect stops. With WoW the whine continues while I play (and is driving me nuts). My video card is the old stock GeForce 5200. the Powermac is the Rev A dual 1.8's. Any ideas on what is causing this? is Core video beating the hell out of my card? Should I call Apple, and if so, how much is phone support? (my 90 days is over, but i'm still in the 1 year warrenty. and sadly the closest apple store is over 2 hours away.) Any insights would be helpful. Thanks in advance!
