Upgrade version vs. oem

[gonintendo]

you can get win7 upgrades on ebay for around $50, so is it worth getting the oem version for ~$50 more?

I would go with OEM 'cause if for some reason to need to do a reinstall you will need to:

1. Reinstall the old OS
2. Install the upgrade

Not sure if "upgrade" requires you to call Microsoft to release the license.

I actually would by Retail instead, but that's about $180 - $190.
