My 2007 macbook is failing hard. I don't have a lot of money, so I am buying an 11" air for $600. My main concern is I'm going to notice a performance hit because all the numbers I see are lower. But I'm a little dumb with how speed works with these things, so I was wondering if someone could tell me if you think I'm really going to notice much. I mainly use my computer for internet, word processing, and photoshop. Here's the specs: Macbook: Memory: 4G RAM 667 MHz DDR2 SDRAM Processor: 2.4 GHz Intel Core 2 Duo Graphics: GMA X3100 Air (Late 2010) Memory: 2 GB 1067 MHz DDR3 Processor: 1.4 GHz Intel Core 2 Duo Graphics: NVIDA GeForce 320M 256 MB I know some things about computers, but I don't really know how the processor, memory, or graphics card affect performance for different things. If someone's willing to give me a quick lesson on that I'd be appreciative! Thanks so much for all your help!
