Hey Guys. I know this has been discussed countless times, but not quite in context with the new Yosemite OS. I'm running public beta (non dev.) on OS X Yosemite and experiences sloppy performance. I did do that before when running Mavericks, though not as much. I know this i probably due to Yosemite still being beta and not having the best memory utilization. Now my question is, would you guys recommend upgrading to 8 or 16 gb RAM? My machine is a early 2011 MBP 13", 2,3 GHz Intel Core i5 with 4GB RAM. I already upgraded to a SSD. I'm mainly using it for browsing and watching movies. I do have the money to go for 16GB but taking in mind that machine is 4 years old, is it worth to pay double the money for 16 GB? Will the CPU limit the performance before 16 GB is even needed? Thanks in advance!
