$245 for 4 sticks of 1gb - Memory America http://eshop.macsales.com/basketHandler.cfm?do=updateBasket $220 for 2 sticks of 2gb - Other World Computing http://eshop.macsales.com/shop/memory/Mac-Pro-Memory Which one should I go for? I heard that more sticks = less latency and better performance. I have 2gb (2x 1gb) of the stock ram coming with my Mac Pro on Monday. Any opinions, suggestions, or feedback would be greatly appreciated. Also, has anyone here dealt with Memory America? Can they be trusted? I have never heard of them before.
