AGP Ports on a motherboard are Accelerated Graphics Port and are traditionally used for graphics cards. AGP was used because it provided a direct, dedicated pathway to the Câ¦PU and memory rather then using the PCI Bus. Currently AGP is being phased out for PCI Express which is considerably faster.
Raw potatoes don't take well to freezing. They don't go bad, but their texture and taste are poor after they've been thawed and then cooked. Blanch them first to inactivate enzymes that cause them to degrade to see if the resulting potatoes are acceptable to you. The fresher the potatoes, the better they freeze.
As Titus mentioned over on facebook, the one downside of storing the potatoes in the fridge and the ensuing sugars is that it makes the potatoes a bit worse for you since it increases their glycemic index. However, I don't think that white potatoes are good for you in any form, so we eat them rarely.
