My answer probably won't be the best one. But I'm answering to provide what may be good insight. I'm not really a computer expert but I'll share what I would think for what it's worth.

You may be able to swap processor chips of the new one is the same size with the same number of pins or whatever they're called. If you're able to do this yourself, be sure to replace the heatsink grease if there is any. It's also known as thermal paste. It effectively takes heat from the processor chip and disperses it through the heat sink or whatever is used to prevent overheating.

If you're not sure if you can do this task, you could try but risk doing something bad to the computer. Also, Apple does not like it when people modify their products, especially notebook computers. They'd rather people take it to an Apple store and pay to have it done for them. Upgrading RAM is a common service they do. They may do processor chips too.

Also to consider is that your notebook computer may benefit greatly from a new processor chip. Or it may not benefit all that much. If not, it could be because the rest of the components are limited in performance. The RAM, motherboard, video/graphics card, and maybe other parts. A computer that comes with a better processor chip is likely to be newer and better able to utilize that chip.

From what i have examine, even as it must be a probability to apply the Phenom in an AM2 motherboard designed for a twin center (AMD X2), the performance heavily isn't there with out the right chipsets for quad center processors. you ought to also opt to substantiate that Gigabyte has released BIOS updates to enable any help for Phenom chips in spite of the performance limits (with the aid of older chipsets). So the easy answer is: per chance, yet likely with a small performance hit.

Wait!!! Wait!! dont go out and buy a quad because they burnout ive had 2 now and they have both burnt out i recommend upgrade your ram and remove programs you dont need.
