I got more imformation from different people. I stand to be corrected you can put an am3 processor in a am2 socket which is what you have.you cant do vice versa . The thing you dont want to do is go up to 65 watt processor for the heat sink will get too hot. the 4850e wich is a 2.5 and the 5050e is a 2.6 is still the best bet. you can get these on ebay just keep checking. Also you might have to change the bios when going to an am3 processor just have to try it ! The motherboard is compatible without replacing it good luck!By the way I put 7200rmp hard drive from seagate and windows 7 ultimate and it rocks!
