My husband bought the acer desktop way cheap (Acer Aspire Revo AR1600-U910H Mini Desktop PC - Intel ATOM N230 1.6GHz, 1GB DDR2, 160GB HDD, HDMI, Windows XP Home). Now that we have it and it is really slow, I would like to upgrade the processor. Would any one know what would be the best upgrade for this? or HOw will I find out whether I will be able to upgrade this with Intel Core 2 quad processor? or later generations? Please help
