If your system is working I would say it's not worth the cost. Performance will be related to what you have now and what you get for a logic board. Review EveryMac's listings to see the numbers on the most part it's not that much a difference given the cost. As to features, there are none within the OS its self between these models. The only notable difference is the speed of the USB port from USB2 to USB3.
