We just downloaded Windows 7 and we love it. I have two questions, though: 1) The base score on my computer is 3.1; the Gaming Graphics is 3.1 and the Desktop Performance for Aeros is 3.4. These are the lowest scores-- the highest is a 5.1 in Disk Data Transfer Rate. Is this okay for a 2007 computer? 2) If it isn't okay, can I change it with software downloads of some sort-- I'm not interested in installing new hardware of any kind. Thanks!
