Hi, Just about to purchase a Apple Power Mac G5, need to know : is going for a dual 2.0ghz Powermac worth an extra £100 on the price?. Seems a daft question but I am on a tight budget and going to have to do some serious legwork to get the additional funds... I shall be using the PowerMac for photo's , web browsing, listening to music and watching films. I won't be using it for any encoding/movie editing etc. So really I am buying it because of OSX more than anything else. Please could somebody advise in real terms what I would notice if I did plum for the higher powered unit. Many thanks..
