Ok I have an 2010 i5 3m L3 cache, 4gb 1067 Mhz DDR3 RAM and 320 GB Storage MBP. I want to upgrade it, what will give me an overall "less slowing down" machine: Upgrading to 8Gb of Ram, or an SSD. I need somewhere between 200-250 gb storage. Also, if RAM is the way to go, where should I buy it? I found the guide not very helpful, so if you bought some, where? I live in Holland if that matters. Thanks for the help!
