Hello guys. well basically i am a sound designer and a music producer. i work allot with Cubase and also work quite a bit with Photoshop. i want to install OSX Lion on my MSI GE620 and i think there may be a few problems. My specs: Intel Core i7 2630QM, 8GB Ram (going to give me a hard time installing right?) 640GB HDD and Nvidia GT 540M. now i know the GPU is going to screw things up for me but is there a way to disable it and switch to the onboard HD3000?? if so, what are the downsides of doing this and is there a way to avoid them? will i have a problem with things such as the thumb pad, wireless internet or camera for example? (drivers etc.) thanks allot!
