Hi, I have convinced my completely non tech savvy father to upgrade at least the CPU of his ancient Dell Dimension 5000 PC, it has a socket 775 motherboard and 2GB RAM. I would like to know what a decent enough dual core CPU would be, and whether there is any risk of upgrading it. Thanks.
That should work, wont be a big performance increase but at that price you might as well.
You should upgrade the Dell's BIOS before changing the CPU, Some CPU's require a BIOS update in order to function properly.
