Currently I'm using a 2007 MacBook. I mainly use it to watch movies, browse web, torrents, etc. What annoys me the most is that it can barely handle 720p videos while the 1080p ones are a constant lag. Forget about full resolution blu-Rays. I'm planning on getting the Mac mini with 16Gb of RAM and solid state hard drive. With that said, I am having trouble deciding whether to get the i5 2.6GHz, 2.8GHz, or i7 3.0GHz. Any suggestions for my current uses?
