Our Desktop PC(XP) has reached the end of its lifespan. I have decided on the 24" iMac because of the VESA mount. Now BB just offered a good discount on the 2.8 version with 24mnth 0% finance. I will add 4gb memory immediately and WD 1TB drive. I will be running parallels with Vista, An elgato video capture, video editing, and on the only game is Zoo Tycoon currently(kids). Will the 2.8 model be enough power? Should I get the 3.0ghz from Apple instead? Should I wait for the new imac? HDMI or eSATA would be nice. Thanks for you time!
