I have just managed to snap up two Mac Pro 4.1's for £350 each. One will be for myself and one for my wife. From what I've seen, they're fairly standard spec so I'm wondering what I should be upgrading. Current specs are (both are the same): Mac Pro 4.1 2.66GHz Quad Core 3GB Ram GT120 GPU We're already going to stick SSD drives in. Is it worth upgrading the CPU? If so, which CPU should I go for? What Ram do I need to look out for and how much should I be getting? We're both going to be moving from using i7 2.2GHz Macbook Pro's as main machines to using the Mac Pro's so want as big a boost as possible, without too much outlay.
