Hello, How are you doing? I currently have a Macbook Pro 17 unibody. It has a C2D 2,66, 4gb of ram, and a 120gb SSD. I use my laptop for general browsing and photography work, like photoshop and lightroom and aperture. I have the possibility of selling my laptop and buy a Nehalem quad 2.66 stock. (3gb of ram, 640gb hdd and GT120). With an Apple LED cinema display. I will put around 1000 euros in the trade, but get to keep my SSD and use it on yhe mac pro as a boot drive. I currently don't need the mobility, has my laptop left my house 2 times in one year. My question is if this is worth it. Will I notice much performance increase? I know I will be going fron a C2D to a Quad CPU with Hyperthreading at the same speed, but do you think it is worth it for 1000 Euros? Look forward to hear your comments! Cheer!
