I'm thinking of switching over to Mac from PC, I'm getting really annoyed at all the spyware and adaware my pc gets, and viruses. I've looked at the iMac 20" 2.0ghz in the stores and I really fell in love with the design, but I'd like to know if it will be powerful enough to do what I need it to do. I will be using it for flash, dreamweaver, photoshop, light video editing, office type apps, internet, watching dvd's and in the future I will probably get a tv tuner for it so I can watch tv on it as well. The only game I will want to play is The Sims 2. Also, how much ram would you recommend? I can afford to go either 1gb ram, or 1.5gb ram, but if there isn't that much difference adding the extra 512mb it could be better to spend the money on something else. Thanks everyone in advance!
