Hey everyone, i've been thinking of adding a 19" 16:10 TFT Monitor i have going spare to my iMac but i have a few questions regarding the issue. First of all will the GPU in my iMac cope with it ok? It's only the 128MB 2400XT and like i say i'm unsure if it will be able to cope with 2 high res displays as well as HD editing and other stuff. Also if it does cope will i see much of a rise in my temp's or not? I don't really want them going higher than they are now, especially my GPU and HD. Last but not least if it does cope and everything fine do i have to download and software to enable this or is it built in to OSX, i just want to be able to drag videos and apps into the other monitor and view them on that. Cheers again!
