I just ordered online a 27in quad I7 imc but I kept the memory at the base level. I will need additional memory but I am under the impression memory can be bought elsewhere for less. After searching the net I see it's not as simple as I had hoped, I'm not finding any links that specifically say the RAM is compatible with the imac and I'd hate to order it and find it wasn't. I am hoping to order an additional 2x4GB, could someone tell me if the RAM on the link below will work, or if they have any other advice/discount links. If not I should probably go back and adjust my order. http://www.pcsuperstore.com/products/T25439-Kingston_Technology-KVR1066D3Q8R7SK28G.html cheers, Colin.
