I am considering upgrading the mobo' in my computer as it only has two pci slots and i need one more. currant board is an msi-6511. New board needs to be mATX as I want to keep my existing case as it fits nicely into it's hole. Other things I would like are DDR Ram and onboard Lan connection as this would free up a usb port. Processor is an AMD Athlon 1.33 (thunderbird).
