Hi Guys, So I have an early 2011 i5 MacBook Pro. Since installing Yosemite it's been painfully slow, basically unusable. I just swapped out my 320gb HD for a 250GB crucial mx200 SSD. I installed Yosemite on the SSD and just transferred a small portion of the data on my HD to the new SSD. The speed increase is astronomic. It's basically as fast as when i first got it. Now I'm considering swapping out my 2 2GB sticks of ram for a couple 4gb sticks. Would I see any tangible benefits from upgrading to 8GB of ram when all I basically do is web browsing, music streaming and office (word/excel/ppt) document editing? I'd like to keep this laptop for another 2-3 years so I'd be more than happy spend the money on an upgrade that will allow me to do that. Thanks.
