Okay...I have a PowerMac G4, the power supply is going out, thought about fixing it, but I need to upgrade my Creative Suite software since I am still in CS. and it requires the Dual Core. I am a graphic designer and work with large files..I have an old Gateway2000 VX900 monitor and I am not sure what to buy that would work. I really don't want to spend too much money...but I want to make sure everything can be compatible. Can some one give me some insight on what to buy? Thanx!
