To say I'm due for a Mac upgrade is the understatement of the century. I've been using my G5 1.6GHz tower on a daily basis since I bought it as a refurb in 2005, and while it still does what is asked of it, I would like a fresh experience. I was originally going to purchase a refurb'd MacBook Pro 17" C2D 2.8GHz from the online UK Apple Store, however as these are due to be updated soon, it might make more sense for me to hold off on the laptop until the summer by which time the prices of the current models will hopefully drop a little more. Seems like the best value Mac desktops at the moment are the 27" iMacs. I'm torn between getting a refurb'd 3.06GHz/4GB RAM/4670 256mb GPU model, or a brand new TOTL i7 2.66GHz Quad with the 4850 512MB GPU. I will be using this machine mainly for simple daily tasks (web browsing, Photoshop photo editing, iChat, iTunes, etc), but will also need to do some HD video capture and editing once I purchase a HD camcorder, and in the future may wish to create a home recording studio using Logic or ProTools lite, etc. Having read several reviews it would seem that I wouldn't get the full benefit from the i7 CPU and 4850 512MB GPU unless I'm a hardcore gamer and do a lot of video editing and need really fast turnarounds. I don't game, and the video editing would only be occasional (e.g. holiday vids), so I'm thinking that a refurb'd 3.06GHz would do the job fine. I'd also be saving myself a whopping around £625 ($950US). Only downside is that you can't appear to customise the refurb'd units in the online Apple store. The one that's on just now ships with 4GB RAM, so if I wanted more RAM I'd need to install it myself, and I don't want to be messing with removing the glass screen! Given that I've got 2GB RAM installed in my G5 1.6GHz running OS 10.3.9 (Panther), I'm not sure if 4GB would be enough on the iMac running Snow Leopard. What do you think? PS - Would I be able to take my refurb'd iMac into my local Apple store and have them install extra RAM into it for me?
