Here is the spec im considering: 13" 1.3GHz (wondering if i should upgrade this? see below) 8gb ram 512gb drive It will be heavily used at work. HEAVY web browsing. Multiple browsers open, as many as 7 sites open on each. I will also push 1 (2 if possible?) external Dell displays Also light Photoshop use, heavy Outlook for emails, AIM for chat, Skype for video calls. Basically im asking the following: 1. Is 1.3GHz enough for my useage or should i up that? 2. will 8GB RAM be enough for me? 3. Doesnt matter, just wondering if i can push 2 external displays? 4. Will the MBA plow through the above? Or do i need the MBP for more power/ram?
