Title says it all. I have a 2010 21.5" EMC 2389 iMac intel i3 550 3.2ghz with 8gb of ram and a 2tb hdd. I'm trying to upgrade a little bit for better image processing and gaming. My mac has started to slow down over the years. I still have plenty of space left on my hdd (over a tb left).

Specifically, the upgrades i'm hoping to make are:

1.) upgrade processor from i3 550 to i3 6320

2.) upgrade processor from raedon hd 5670 to hd 5970

3.) upgrade from 8gb of ram to either 12 or 16.

4.) if the community has good things to say about hybrid ssd/hdd drives then i'd like to upgrade to the 2tb ssd hybrid sold on the ifixit site.

Please give thoughts and tell me if all of these upgrades CAN be done (I have someone with the experience to handle this) If all of these cannot be done, could you please work with me to help me find the best options for me and my computer?

Thanks in advance,

~Carter
