Hi there, i have a 2.4 i7 8bg 15 inch and im into video editing, Final Cut After Effects and Photoshop. Using Leopard will i consume less from ram than using Lion? I notive with all that thing, dock and all this new things.. I usally work in all of the programs open at same time. and i was thinking in downgrade to leopard to get better use of mine 8gb of ram. rather of giving it to OS. I get windowserver using 3.2 gb. where is he using all this? Thanks a lot.
