Doing some cross referencing, Im unable to figure out what the biggest CPU I can put in my Motherboard is. Im currenty running a budget 2800Sempron in my gigabyte GA-7NF-RZ(C). Its painfully slow, and showing its true colors in being a cheapo. I would like to upgrade, but dont know what I can upgrade to. It will be awhile anyway, as I will have to start saving for one as money is non existant.
