Hello, I have a question about a MacBook Pro. I am looking to buy one used and I have a few that I have pending. Here are the two I have in mind: MacBook Pro: Model Name: MacBook Pro Model Identifier: MacBookPro5,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.66 GHz HD Capacity: 1TB HSSD Total Number Of Cores: 2 L2 Cache: 6 MB Memory: 4 GB Mac Mini: MC815LL/A 2.3GHz dual-core Intel Core i5 with 3MB on-chip shared L3 cache 8GB of 1333MHz DDR3 memory 500GB (5400-rpm) hard drive Intel HD Graphics 3000 processor with 288MB of DDR3 SDRAM shared with main memory I know that I wrote that I am looking for a MacBook Pro and I posted a Mini for the second option, but what I am really looking at are the specs. I like the idea of having a MacBook for mobility, but a Mini wouldn't bad for me, either. Anyhow, the Mini specs are what I would be looking at with a MacBook, as well. So, my question: How much faster is the i5 compared to the Core 2 Duo that I have listed? Will I notice much of a performance difference when using applications such as Photoshop, Illustrator, Dreamweaver and Garageband? Thank you in advance for any and all help!
