personally, i say option 5... best... BUT, thinking smarter i say option 4, same money better parts. onoy reason i say 5 is because its a dual core amd and they are one hell of a processor. i do think that they are screwing you for having to pay the setup fee again. but i think that for 1-2 days of downtime and the same price it would be benefitial to switch to the new hardware.
