Hello, I just took the plunge, ordered a 27" i7. I figured since I'm already $2300 in the hole to apple, that I simply cannot afford to upgrade memory through them. To upgrade to half the capacity with 2x4GB through apple costs about as much as getting 16 GB aftermarket. I'm probably just going to get 4x4GB and be done with the ram upgrades for this machine. I thought about doing 2x2GB + 2x4GB for a total of 12 but I think I'd rather just max this biatch out before the reality of what I'm spending fully sinks in. Question to fellow imac owners: What brand or brands of ram do you recommend? I have looked all over but it seems like reviews of a bunch of different 3rd party 1333mhz ram that some people had problems. I'm sure people with problems are the ones who tend to write reviews, but I really just don't want to be one of those people. I'm not above spending more than the minimum to go with a solid company with a good product (hence the imac). I'm looking for personal opinions on brands here, not what is the best deal at this very moment in time. Any suggestions? fwiw: i7 3.4 GHZ, 4GB ram (for now), 2GB Radeon 6970m, 1 TB (ssd + 1TB + thunderbolt raid eventually).
