I've been a mac user for a couple of years now, but i'm not very tech savy. i've owned a macbook pro for a few years now and i'm looking at getting it refurbished, as its getting a little long in the tooth. these are my machines specs that i've taken from system profiler. im pretty sure its an 08 model, but i've had it for so long i've forgotten :/ Hardware: Model Name: MacBook Pro Model Identifier: MacBookPro4,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.5 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 6 MB Memory: 4 GB Bus Speed: 800 MHz Boot ROM Version: MBP41.00C1.B03 SMC Version (system): 1.28f3 Graphics/displays: NVIDIA GeForce 8600M GT: Chipset Model: GeForce 8600M GT Type: GPU Bus: PCIe PCIe Lane Width: x4 VRAM (Total): 512 MB Vendor: NVIDIA (0x10de) Device ID: 0x0407 Revision ID: 0x00a1 ROM Revision: 3212 I mainly use this machine for designing and also a bit of animation/video work and would like to start exploring the area of 3d graphics and animation. I dont have a huge budget and a friend suggested that i should look at refurbing this machine rather than getting a new one. I'd really appreciate some advice on what to ask for and what is possible for my machine, rather than walking into some store and potentially getting taken for an expensive ride.
