qw12345 :
Since it is an old computer i figured any upgrades would be pretty cheap.
The BGA 437 socket just doesn't have any strong processors for it. It's meant for Intel Atom CPUs, which are mostly for netbooks. Any upgrades on that socket wouldn't be worthwhile, unfortunately. I haven't checked whether the PC you listed is a laptop or a desktop, but if it's a laptop (as most Atom PCs are) then the CPU is probably soldered to the motherboard anyway.
