Hi guys, I am hoping to purchase the high end 27" iMac (i7) when Apple refresh the iMacs (hopefully soon). I am thinking about upgrading the RAM to 12GB having recently seen a post by Hellhammer saying that you can combine 2 x 4GB with 2 x 2GB. If I were to just buy the iMac from Apple without any RAM upgrades then I get the 2 x 2GB modules leaving me to find a suitable vendor for the 2 x 4GB. Crucial RAM sells the 2 x 4GB modules for £386.56. Or, with Apple I could custom order the iMac with 2 x 4GB modules for £320. I could then buy the extra 2 x 2GB modules off of Crucial for £92 to add up to 12GB in total. Option A (non Apple) comes to £386.56 Option B (with Apple) comes £412. So it seems a no brainer to buy outside of Apple but I was wondering if there are any other cheaper sites for iMac RAM than Crucial. I have always though that Apple RAM was horrificly overpriced although in this case it's not that much extra. To the GPU side of things: I was wondering what people's thoughts are on the possibility of there being 1GB of dedicated RAM in a future iMac graphics card? Thanks for reading.
