Hey guys just writting up my Review to help out any fellow members with purchasing ram. After reading the forum regarding ram, i decided to go with http://eshop.macsales.com to get my ram. So going to the site was really easy. First i clicked memory from the top tabs selection. Then i checked my computer on the right side (iMac). Then i checked the memory option on the bottom and search... I got a return of all the ram available for my computer. 512mb, 1gig, singles or pair, etc... Well i went with 2gig pair. I used to have 1 gig. I chose the 2.0gb kit micron factory original (1gb x 2 matched pair). The delivery option was i believe usps, ups, fedex. So i figured the regular shipping was only like .50 cents away from ups 2 day delivery ... So i went with 2 day ups delivery. I placed my order around 7pm. I recieved it in 2 day. Installation was quick, and let me tell you i do feel the difference here in there. Like when i open up iphoto, to go up and down, i see it's more quicker, reopening web pages is quicker as well. I'm exteremly happy with my puchase, and would buy from them again, i would also reccomend them. NOW, i'm ready to take on Leopard!!! Tomorrow can't wait to go buy it!
