I'm sure this has been discussed many times before, but right now I'm torn between two systems - Refurb 24'' iMac, 2.8, 2GB Ram, 320GB, Superdrive, 2600 Pro - £949 Self-build PC, Q6600, 8GB Ram, Radeon 4850, 1TB Hard Drive, Blu-Ray writer, 23'' Full HD monitor - £949 My question is...faced with these specs, why on earth choose the iMac? I know a lot of people on here mention design as one of the main reasons they prefer Macs, but let's be blunt - design doesn't get the job done, the specs do. My main reasons for buying a new computer is for 3D rendering, compositing, and HD video editing (including AVCHD). Does OSX really justify the cost of such an outdated system in terms of technology? I'm not looking to troll at all, I'm just questioning which would really be best and would like honest, impartial opinions. Please no fanboy rants.....?
