Hi all, I need some advice from you peeps on here on determining how much my mac is valued at roughly in the used market at the moment. Here are my mac's specs: 15" Mid 2010' Macbook Pro Processor 2.66 GHz Intel Core i7 Memory 4 GB 1067 MHz DDR3 Graphics NVIDIA GeForce GT 330M 512 MB Software Mac OS X Lion 10.7.2 (11C74) 500GB 7200-rpm hard drive I have the original box, accessories, etc. Please advise. Thank You in advance to anyone who posts. Im looking at getting back into a desktop as I really have no use for a laptop. Thinking of getting into one of the 27" iMac's available with the i5 chip, 8GB of RAM, a SSD and the AMD Radeon HD 6770M with 512MB graphics card. Some advice on perhaps comparing my current computer to the one Im thinking about getting into would be appreciated as well!
