Hi, I really need a desktop computer that can convert a lot of DVD's to h.264 using Handbrake. I will also be doing a lot of Tunebite work using Bootcamp, converting my music collection to mp3 format. What would suit me better a Mac Pro or an iMac. If I go for an iMac I would have to purchase the 20" version as the 24" version would be far too big for my small bedroom. However this limits me to a 2.66ghz processor. Would this be adequate for fast encoding? Would a Mac Pro be overkill? I don't play games or do any other massively intensive tasks other than using handbrake a lot and tunebite. However, I do currently have a Dell 20" 2007wfp monitor. Really appreciate your thoughts on this, as I am finding this very difficult.
