Hi everyone.... I'm about to push "Buy now" on a used Power Mac G5 Dual1.8ghz with 2.5GB RAM. I'd like to ask, has anyone edited (Home video) HD videos on these units? I dont make documentaries or musical videos or complicated things. I just want to edit family videos and with my ex 400mhz G4 (sold) it was a impossible. I even sold recently a dual 800mhz quicksilver since it was so painful to edit that my eyes would bleed. Can they handle it? I'm without a Mac right now and the auction is going to end pretty soon. I really need your input. Thx.
