"Upgrade Chance" is a probability of a successful processor upgrade/downgrade from the Xeon X5260 (original CPU) to a specific model. This number is calculated as a percentage of all motherboards, compatible with both original and upgrade CPUs, compared to the number of motherboards, that support the original Intel X5260. The number "100%" means that all motherboards, that work with the original model, also work with the upgrade CPU. The number "0%" means that none of the boards, that support the original CPU, will support the upgrade processor. The manufacturers do not always test or publish results for obscure and unreleased models, and in some cases for OEM only processors, as a result they tend to have much lower scores than more common desktop/mobile counterparts.
