To edit videos on the highest setting with a Canon vixia hf s21 (http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=177&modelid=19827#ModelTechSpecsAct) on a cheap imac with sony vegas pro 9 (http://www.pricescan.com/Apple-iMac-21.5-inch-3.06GHz-MB950LL-A/co/266700.html) Sorry i know nothing at all about cameras and editing. But i want to and i heard the vixia hf20 needed like a really good computer to be able to edit and alot of people edit on macs. And i dont know if i would be able to on this mac because this one has NVIDIA GeForce 9400M graphics while the others have ATI Radeon HD 4670 graphics with 256MB I hope this makes sence and i dont sound dumb. lol thanks
