Well title says it most but not all so let me elaborate. I have an early 2008 model 2.66, 320gb iMac. I love it, it's smooth with normal operations and most video and photo work I do (family stuff, nothing serious). However, it is getting a bit on the older side and I have a new 1080p/60 camera that shoots amazing footage but my Mac can barely render it in Elements and takes a very long time in iMovie to do it. I do not use FCP so I couldn't tell you how that goes. By looking at eBay and Craigslist I see prices of $550-$650 for my Mac which I would later turn around and buy a Mac Mini. I'm leaning toward the 2.5ghz dual-core because of the discrete graphics card which I think would come in handy for the HD Video editing. So what do you guys think, would I see a big improvement in speed and performance for a price difference of roughly around $100-$150 after I sell my iMac? I have a couple more questions but I'll wait until I hear some thoughts. ThankS!
