Hi Folks My 6 year old MBP and 5 year old Mac Pro are getting a bit long in the tooth. the Pro's going to retire to the cellar to live its retirement as a media server/NAS and the MBP is just about OK for the kids to play some online games... Both will be superceeded by a nice new rMBP. Now I'm really not sure which rMBP to buy. To be honest, the base model is probably enough in most departments for my needs, but I'm an Aperture user and I've had a lot of problems in the past on my Mac Pro with memory usage. When I was running on 9GB it was swapping like hell when Aperture was running. So I'm a bit frightened that if I do buy the 8GB memory rMBP it's going to come-up a bit short. On the other hand, if I'm going to upgrade the RAM then I may as well get the higher spec, but then we're talking some serious wonga difference in price, around 800, I'm thinking "why not get the cheaper model then hand it down to the kids next year and get a new one etc." So, anyone here using Aperture on an 8GB rMBP and how does it perform? Cheers!
